==Paleoindian==
The Paleoindian period in North America dates to about 9,500-7,500 B.C. Paleoindians in Iowa encountered vastly different environments than those of the recent past. The climate was cooler and wetter than present averages. In north central Iowa, Paleoindians lived in recently deglaciated landscapes covered by boreal and conifer-hardwood forests, shifting through time to elm- and oak- dominated woodlands. Woodlands predominated in most of the state as well, and prairie, if present, was very limited.
The Clovis complex is the earliest well defined archaeological culture currently known in North America. Clovis and other fluted projectile point styles were made during the first two-thirds of the Paleoindian period, and Dalton and unfluted point forms date to the latter one-third of the period. Aside from these lanceolate (lance-shaped) points, defining characteristics of the Paleo-Indian period include distinctive butchering tools, extensive use of exotic chert types, and specialized lithic technologies. Fluted and unfluted point forms have been recovered as surface finds from upland and valley locations throughout Iowa.
Paleoindian peoples were extremely mobile, hunting various animals including now-extinct large mammals such as mammoth, mastodon, and giant bison. Most Paleoindian sites so far located in the United States are large mammal kill sites, and little is known of other site types. No Paleoindian base camps have yet been documented in Iowa. To date, the best documented fluted point site in Iowa is a plow-disturbed cache of Clovis points known as the Rummells-Maske site in Cedar County.
==Archaic==
The Early Archaic period (7,500-5,500 B.C.) is viewed as a somewhat transitional period between cultures relying on big game for subsistence and those with a more rounded forager adaptation. Environments changed relatively quickly, as deciduous woodlands, mixed with prairies in western areas, became established over most of the state. Populations probably depended on bison in western Iowa and on deer and elk in eastern Iowa. These large mammals were supplemented by smaller game and by increasing use of plant foods. Settlement types included somewhat permanent base camps and seasonally occupied resource procurement camps. Excavated sites, such as the Cherokee Sewer site, suggest local populations were small and that they were tied to a seasonal round of resource exploitation. Representative artifacts include medium to large spear points, often with serrated and beveled blade edges.
The Middle Archaic period (5,500-2,500 B.C.) is so poorly known in Iowa that it has normally been lumped with the Early Archaic. Cultural adaptations may have been similar, but environmental conditions became increasingly arid throughout the period. The Middle Archaic period corresponds to the warmest and driest postglacial period, commonly referred to as the Atlantic episode, or the Hypsithermal. Human populations throughout the Midwest gravitated to the wetter river valleys, and because of this, Middle Archaic sites are often deeply buried and difficult to locate. During the Hypsithermal, great masses of silt filled river valleys, and alluvial fan development was rapid. Many Middle Archaic sites are buried in these alluvial sediments.
By the Late Archaic period (2,500-500 B.C.) the Midwest was becoming a fairly crowded place with the incidence of intergroup encounter rising sharply. This situation resulted in similar subsistence strategies over broad areas, but also in increased territoriality, local differentiation in artifact styles, and development of intergroup trading networks. The end of the dry Hypsithermal resulted in increased stability of the resource base and made many previously unsuitable areas attractive for settlement. Population levels appear to have increased substantially, and a somewhat sedentary lifeway as well as construction of large ossuaries (multiple-interment cemeteries) are documented for this period. The use of communal cemeteries reinforces the interpretation that populations were becoming more sedentary.
==Woodland==
The Woodland tradition (500 B.C.-A.D. 1000) was characterized by improved technologies, such as ceramic production and horticulture, leading to an overall increase in productive efficiency, and by the construction of burial mounds. Although these characteristics originated during the Archaic, only after 500 B.C. did they come together and become adopted over a wide area.
Woodland peoples refined their hunter-gatherer adaptations, making heavy use of fish and clams in majorriver valleys, and continuing to exploit deer and bison. Dependence on cultivated plants increased. Native plants often thought of as weeds today were grown for their nutritious seeds. Woodland farmers developed domesticated varieties of some of these native grain crops long before corn or beans became important. Climatic conditions approached modern averages, landform development stabilized in most places except in flood plains and stream channels, and vegetation patterns were much like the forest-prairie mix documented by nineteenth-century land surveys.
Early Woodland settlements (500-100 B.C.) in the Midwest were small and seasonally occupied. Early Woodland subsistence patterns in Iowa are not well known, but they probably involved broad-based procurement of mammals, birds, and aquatic species. Early Woodland peoples built large burial mounds similar to some in Ohio, and they interacted with groups throughout the Midwest, as evidenced by artifacts made of exotic raw materials. The typical Early Woodland spear point was a straight stemmed or contracting stemmed point, and pottery of the period includes both a thick, flat- bottomed type (500-300 B.C.) and a thinner, bag-shaped type often decorated with incised lines in geometric patterns (300-100 B.C.). Early Woodland sites are relatively common in the Mississippi Valley but are difficult to identify in central and western Iowa. Perhaps groups on the eastern Great Plains retained an Archaic lifestyle during this period.
The Middle Woodland period (100 B.C.-A.D. 300) is noted for its refined artworks, complex mortuary program, and extensive trade networks. Middle Woodland communities throughout the Midwest were linked by a network archaeologists refer to as the Hopewell Interaction Sphere. Trading involved materials such as Knife River flint from North Dakota and obsidian from the Yellowstone Park area. Also exchanged through the Hopewell network were artifacts of marine shell, copper, mica, and several pipestones, as well as high quality ceramic vessels and possibly perishable materials which have not survived archaeologically. Elaboration of the mortuary program and social stratification indicate increased levels of social and political complexity. However, most Middle Woodland peoples probably lived in small communities or farmsteads, focusing their subsistence economy on food resources in large river valleys and tending gardens of squash, tobacco, and native grain crops such as marshelder and goosefoot. Typical Middle Woodland tools included broad, corner-notched spear points and finely made, thin blades.
By Late Woodland times (A.D. 300-1000) the continent-wide exchange of exotic goods declined but interaction between communities and tribes continued. Population levels apparently increased rapidly. In some parts of Iowa, Late Woodland peoples aggregated into large, planned villages, but in most of the state settlements continued to be small and generally became more dispersed across the landscape. Uplands and small interior valleys became settled or more heavily utilized. Late Woodland peoples introduced the bow and arrow into the Midwest. Continued native crop horticulture and diversified hunting and gathering provided the subsistence base through most of the period. Corn was introduced to many groups after around A.D. 800 but did not form a staple crop until the Late Prehistoric period.
Mound construction was generally simpler than in the Middle Woodland period, but regular aggregations for ritual and other purposes are probably reflected in the Late Woodland mound groups found throughout the state. Groups of linear, effigy, and conical mounds in northeastern Iowa form a distinctive element of the Effigy Mound Culture (A.D. 650-1000). The living sites of Effigy Mound peoples show a seasonal settlement pattern involving fish and shellfish collection during warm seasons in the main river valleys, nut harvesting in uplands in the fall, and winter use of rockshelters. Effigy Mound populations may have lived in dispersed groups in the interior of northeast Iowa during much of the year, coalescing regularly in the Mississippi valley to exploit the vast array of seasonally available resources. The effigy mound groups along the Mississippi bluff line may have signified the territories of loosely related nuclear or extended family units which met seasonally and merged into a larger social unit.
==Late Prehistoric ==
The Plains Village pattern appeared in Late Prehistoric times (A.D. 1000-1650) marking the beginning of a distinctive adaptation to the tall grass prairie/short grass plains ecotone of South Dakota, Nebraska, western Iowa, and southern Minnesota. Improved corn varieties, garden surpluses, new storage methods, earthlodge houses, and a complex social organization were common to these Late Prehistoric villagers. Bison meat was a common item in the diet, and hides were processed for clothing, robes, and coverings for tipis and lodges. Bison bones were modified into a variety of tools such as scapula hoes, used in gardening and digging.
One of the earliest of the Plains Village cultures was Great Oasis. Great Oasis culture developed from the local Late Woodland culture around A.D. 1000. Great Oasis sites are found over a wide area in the eastern Great Plains. Villages were situated on low terraces above the flood plains of rivers and streams, and on lake shores. Large, permanent villages may have been occupied by the entire popu lation throughout the fall, winter, and spring. Smaller, temporary campsites were used for seasonal procurement of resources. During the summer a communal bison hunt or the establishment of small campsites for horticultural purposes may have led to temporary abandonment of the large settlements.
Mill Creek, a northwest Iowa culture of this period, is part of what prehistorians refer to as the Initial variant of the Middle Missouri tradition. Mill Creek villages appear as deep midden deposits on terraces above the Big and Little Sioux rivers and their tributaries. Many of the well planned, compact villages were fortified with log palisades, and encircling ditches. Within the villages were individual earthlodges with large internal storage pits. Mill Creek people were semisedentary horticulturalists who grew a large amount of corn along with the native crops, possibly using ridged-field agriculture. It is likely that, as with other Plains Village groups, a communal bison hunt was conducted on one or more occasions during the year. Mill Creek people maintained connections, possibly through trade, with major prehistoric centers in the Mississippi valley, such as the famous site of Cahokia near St. Louis.
The Central Plains tradition consisted of cultures in Kansas, Nebraska, western Missouri, and southwestern Iowa. Many Central Plains sites were settled farming communities whose residents built substantial earthlodge houses. The archaeological remains of communities along the Missouri River in eastern Nebraska, southwestern Iowa, northwestern Missouri, and northeastern Kansas are grouped into what is called the Nebraska phase. Any relationships between the prehistoric Nebraska phase and historic tribes are unclear, although the historic Pawnee may have roots in the Central Plains tradition. Over 80 Central Plains earthlodges have been recorded in the Glenwood locality, Mills County. They represent a fully-developed expansion of Nebraska phase people into southwestern Iowa around A.D. 1050-1250. Glenwood settlements were individual farmsteads or small clusters of earthlodges dispersed along ridge summits, low terraces, and valley wall slopes in the Loess Hills and adjacent landforms.
During the Late Prehistoric period the Oneota culture dominated much of eastern Iowa as well as extensive parts of central and northwestern Iowa. Oneota peoples lived throughout the Midwest between around A.D. 1050 and 1700. Oneota villages were large and permanent or semipermanent. Houses varied in form from small, square or oval single-family dwellings to longhouses with many families. The subsistence economy was based on fishing, hunting, plant collecting, and agriculture. Distinct Oneota groups occupied widely separated regions of Iowa. Each group, or phase, occupied a core locality where villages were densely packed on the landscape. These core areas are surrounded by huge territories that were probably used for hunting, gathering, and other resource procurement. Although the various phases appear to have been generally autonomous, there was probably a great deal of interaction and socio-political cohesion among them. Oneota complexes are ancestral to several midwestern tribes such as the Iowa, Oto, Missouri, and Winnebago.
==Historic Indians and Euro-Americans==
Several Oneota sites in northeastern and northwestern Iowa bridge the prehistoric and historic eras (A.D. 1640-1700). Early French trade goods such as glass beads, finger rings, and gunflints are found at sites dominated by native-made material. In Iowa the term "protohistoric'' denotes this period, when European goods were arriving and other influences were felt but before European peoples started to make extensive written records of the area.
Indian groups residing in or using portions of Iowa seasonally in protohistoric times included the Iowa, Oto, Omaha, perhaps the Missouri, and the Middle and Eastern Dakota. These groups were essentially sedentary, but elements of their populations made wide-ranging seasonal forays for hunting and warfare.
After around 1650, European competition for tribal alliances and trade, and European diseases, drastically changed the structure of and relationships among Indian groups. Tribal population declined and white dispossession of traditional territories became common. In Iowa, the tribes mentioned above gave way to Great Lakes groups including the Sauk, Mesquakie (Fox), Winnebago, and Potawatomi. Perhaps the best known of these groups among Iowans is the Mesquakie.
The name Mesquakie means "people of the red earth." Oral history indicates a tribal origin in the lower Great Lakes. At the time of earliest French contact, the Mesquakies had recently moved from Michigan to Wisconsin. In the early 1700s French pressure forced the tribe into Illinois. By 1750, the Mesquakies considered Iowa their homeland, and they established priority rights to the Iowa River valley by 1800. Further pressured by white incursion into Iowa, the Mesquakies ceded Iowa lands in 1804, 1832, 1836, 1837, and 1842. Most Mesquakie people continued to live in villages in the Iowa River valley, moving farther up river with each land cession. Some Mesquakies remained in Iowa even after the "official" removal of Indians from Iowa in 1845. In the 1850s, the Mesquakies residing in Iowa and those returning from western reservations purchased land in Tama County, and the Mesquakie settlement was legally founded.
European-sponsored enterprises affecting Iowa in the early Historic period included the fur trade and, in northeastern Iowa, lead mining. In 1762, the area that is now Iowa came under Spanish rule. The Mines of Spain State Recreation Area, Dubuque County, is a portion of Julien Dubuque's original land grant which he received from the Spanish government in 1796. The Mesquakie Indians, who moved into the area in the mid-1770s, allowed Dubuque to mine for lead in what they considered their territory from 1788 to Dubuque's death in 1810. Two other Spanish land grants were given to private individuals-one to Basil Giard in what is now Clayton County and one to Louis Tesson in what is now Lee County. The United States obtained Iowa as part of the Louisiana Purchase in 1803, and soon thereafter President Jefferson sent Lewis and Clark to explore the Louisiana Purchase. They traveled up the Missouri River in 1804, meeting with the Oto and Missouri tribes and hunting in the Loess Hills. In 1809, Fort Madison was built, followed by Fort Armstrong at Rock Island, Fort Crawford at Prairie du Chien, and Fort Atkinson in Winneshiek County. In 1833, much of eastern Iowa was opened for non-Indian settlement and by 1850, small towns were scattered across the state. Early settlements were along rivers, especially in eastern Iowa. By 1870 railroads had spread across the state, and river transportation declined in importance.
Most of Iowa's cities and towns were established by the mid-1800s. Farms covered the state, and industries such as coal mining flourished. By the time of statehood in 1846, the character of modern Iowa had been formed by events of its most recent history.

Geological History

Bedrock Map of Iowa

Oldest Surviving Rocks on Earth - 4.4 billion years ago

Earliest Life on Earth - 3.8 billion years ago

  • Formation of a greenstone belt of the Isua complex of the western Greenland region, whose rocks show an isotope frequency suggestive of the presence of life.

Last Universal Common Ancestor (LUCA) - 3.5 billion years ago

Photosynthesizing cyanobacteria evolved - 3 billion years ago

  • Developed a form of photosynthesis that produced oxygen as a waste product. The oxygen concentration in the atmosphere slowly rose, acting as a poison for many bacteria, eventually triggering the Great Oxygenation Event. The Moon, still very close to Earth, caused tides 1,000 feet (305 m) high.
Precambrian

Reddish outcrops of Sioux Quartzite, a rock of durable quartz grains, are found in the extreme far northwest corner of Iowa. This is the oldest bedrock seen anywhere in Iowa at about 1.6 billion years.

"A small amount of Precambrian rock is exposed in the northwest corner of Iowa in Gitchie Manitou State Preserve. These reddish-colored rocks are the1.6-billion-year-old Sioux Quartzite, a metamorphic rock formed from nearly pure quartz sandstone. Other Precambrian-age rocks elsewhere across the state lie deeply buried beneath thousands of feet of sedimentary rocks. No fossils are known from these Precambrian rocks." The Precambrian in Iowa

Paleozoic Era - 540-240 million years ago

  • Includes the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian periods

The bedrock of Iowa is most easily observed in northeast part of the state. Here sedimentary rocks of Paleozoic age, the Paleozoic Plateau, dominate a scenic region called the Driftless Area. Intriguing caves, springs, and sinkholes, known as “karst” features, result from the flow of underground water through natural vertical and horizontal fractures in the shallow limestone and dolomite.

Cambrian - 541-485 million years ago

2CambrianFarNEIowa.jpg
  • Most modern phyla of animals appear in the fossil record in the Cambrian Explosion, 535 million years ago
  • Earliest known footprints on land - 530 million years ago
  • the supercontinent Pannotia begins to break up, most of which later became the supercontinent Gondwana

"A shallow sea flooded what is now Iowa during Late Cambrian time. The layers of sedimentary rock of this age represent deposition along shoreline, shallow marine shelf, and offshore shelf environments. Cambrian rocks are exposed best in far northeastern Iowa, in a topographic region called the Paleozoic Plateau. Although not abundant, fossils of inarticulate brachiopods, trilobites, algae, and burrows of wormlike organisms have been found in some of the state’s Cambrian rocks." The Cambrian in Iowa

Ordovician -485-443 million years ago

3Ordovician.jpg
  • The most common forms of life were trilobites, snails and shellfish.
  • The first arthropods went ashore to colonize the empty continent of Gondwana.
  • By the end of the Ordovician, Gondwana was at the south pole, and early North America had collided with Europe, closing the Atlantic Ocean.
  • Glaciation may have caused the Ordovician–Silurian extinction event, in which 60% of marine invertebrates and 25% of families became extinct.

"During Early Ordovician time, Iowa stood at the edge of a warm, shallow sea. Interplay between this sea and its coastline resulted in alternating deposits of carbonates and sandstones. Algal remains are common fossils from this time interval. The sea retreated briefly, and then advanced to the north, well past Iowa. Hence, depositional environments in Iowa became successively deeper. The limy sediments deposited in this sea became the limestones and carbonates now exposed in the northeastern part of the state. The sea hosted a diverse and luxuriant marine fauna, including algae, clams, snails, nautiloid cephalopods, corals, trilobites, and bryozoans. The rock units also contain thin, but widespread, bentonites (altered volcanic ash beds), indicating volcanic activity somewhere in the region. By the end of Ordovician time, the seas had retreated from Iowa." The Ordovician in Iowa

Silurian - 443-416 million years ago

4Silurian.jpg
  • Fully terrestrial life evolved, including early arachnids, fungi, and centipedes.
  • The evolution of vascular plants (Cooksonia) allowed plants to gain a foothold on land. These early plants were the forerunners of all plant life on land.
  • During this time, there were four continents: Gondwana (Africa, South America, Australia, Antarctica, Siberia), Laurentia (North America), Baltica (Northern Europe), and Avalonia (Western Europe).

"Shallow seas covered Iowa during the Silurian, and the rocks of this time interval are predominately dolostones, found today in the eastern part of the state. These rocks formed from limy muds that accumulated on the ancient sea floor. The first large-scale reefs formed during the Silurian, although these structures were more like muddy “mounds” than the reefs growing in the tropics today. The preserved remnants of some of these reefs can be seen in eastern Iowa, where fossils include distinctive "chain corals," numerous species of brachiopods, snails, and other marine invertebrates." The Silurian in Iowa

Devonian - 416-359 million years ago

5Devonian.jpg
  • Also known as "The Age of the Fish", the Devonian featured a huge diversification of fish, including lobe-finned fish which eventually evolved into the first tetrapods.
  • On land, plant groups diversified incredibly in an event known as the Devonian Explosion when plants made lignin allowing taller growth and vascular tissue: the first trees evolved, as well as seeds.
  • The first amphibians also evolved, and the fish were now at the top of the food chain.
  • Near the end of the Devonian, 70% of all species became extinct in an event known as the Late Devonian extinction

The Fossil & Prairie Park by Rockford features Devonian fossils. In addition, the bedrock under the Longnecker House is also Devonian.

"Warm, shallow seas covered Iowa during Devonian time. These waters were home to numerous marine invertebrates including abundant brachiopods, trilobites, rugose and tabulate corals, and echinoderms, and, for the first time, a variety of fish. Reefs flourished in the state; stromatoporoids (extinct organisms related to sponges) formed variously shaped colonies that resembled layered mats, branches, and rounded masses. Large colonial and solitary corals joined these sponges to form extensive reefs, some of which can be traced for over 100 miles in eastern Iowa. Many of these fossils can be seen at Devonian Fossil Gorge, several miles upstream from Iowa City along the Iowa River." The Devonian in Iowa

Carboniferous - 359-299 million years ago

Carboniferous Period Rocks
  • During this time, average global temperatures were exceedingly high; the early Carboniferous averaged at about 20 degrees Celsius (but cooled to 10 °C during the Middle Carboniferous).
  • Tropical swamps dominated the Earth, and the lignin stiffened trees grew to greater heights and number.
  • As the bacteria and fungi capable of eating the lignin had not yet evolved, their remains were left buried, which created much of the carbon that became the coal deposits of today (hence the name "Carboniferous").
  • Perhaps the most important evolutionary development of the time was the evolution of amniotic eggs, which allowed amphibians to move farther inland and remain the dominant vertebrates for the duration of this period.
  • Also, the first reptiles evolved in the swamps.

"Warm, shallow seas covered Iowa during the Early Carboniferous (Mississippian). Spectacular fossils of crinoids and asteroids (“starfish”) have been collected from rock layers of this time, and lacy bryozoans, cephalopods, and other marine animals are common in the limestones and shales. As the sea retreated from Iowa at the close of the Mississippian, a sequence of river and lake sediments was deposited. Some of the world’s oldest amphibian fossils have been recovered from these layers of rock in east-central and southwestern Iowa.

Late Carboniferous (Pennsylvanian) rocks are quite extensively exposed in southwestern Iowa. Multiple cyclothems, repeating patterns of marine and non-marine sediments, indicate numerous advances and retreats of a shallow sea over this part of the state during this time. Seed ferns and scale trees were common in the coastal swamps adjacent to the sea. Their fossils can be found in abundance in some of these rocks. During the late 1800s and early 1900s, coal resulting from the rich plant life was mined extensively. Iowa’s Pennsylvanian rocks contain large reserves of coal, but its high sulfur content has discouraged continued extraction." The Carboniferous in Iowa

Permian - 299-252 million years ago

7Permian.jpg
  • At the beginning of this period, all continents joined together to form the supercontinent Pangaea, which was encircled by one ocean called Panthalassa.
  • The land mass was very dry during this time, with harsh seasons, as the climate of the interior of Pangaea was not regulated by large bodies of water.
  • Diapsids and synapsids flourished in the new dry climate. Creatures such as Dimetrodon and Edaphosaurus ruled the new continent.
  • The first conifers evolved, and dominated the terrestrial landscape.
  • Near the end of the Permian, however, Pangaea grew drier. The interior was desert, and new species such as Scutosaurus and Gorgonopsids filled it.

The Permian–Triassic extinction event, aka "The Great Dying - 251 million years ago

  • Eliminates over 90-95% of marine species. Terrestrial organisms were not as seriously affected as the marine biota, but still take 30 million years to recover.

"The seas had retreated from the state by the Permian. The surface of the future state of Iowa was exposed and undergoing extensive erosion, thus there are no Permian rocks or fossils found anywhere in the state." The Permian in Iowa

Mesozoic Era - 251.4 Ma to 66 Ma

  • Contains the Triassic, Jurassic and Cretaceous periods - dinosaurs!

Triassic (251.902 to 201.3 million years ago)

7Permian.jpg

"The seas had retreated from the state by the Triassic. The surface of the future state of Iowa was exposed and undergoing extensive erosion, thus there are no Triassic rocks or fossils found anywhere in the state." The Triassic in Iowa

  • Triadobatrachus massinoti is the earliest known frog - 250 million years ago
  • Sturgeon and paddlefish (Acipenseridae) first appear. - 248 million years ago. Examples of these types of fish still swim in the Mississippi River, and larger connected rivers.
  • Earliest dinosaurs (prosauropods), first mammals (Adelobasileus) - 225 million years ago


The Triassic/Jurassic Extinction - 205 million years ago

  • wiped out most of the group of pseudosuchians and gave the opportunity of dinosaurs including the Apatosaurus, Tyrannosaurus, Perrotasaurus, and Stegosaurus to enter their golden age.

Jurassic (201.3 to 145 million years ago)

9JurassicFtDodgeGypsum.jpg

"By Late Jurassic time, the Western Interior and Great Plains regions were flooded by the Sundance Sea. The edge of this sea extended into central Iowa, resulting in the deposition of sediments associated with embayments and lagoons of the coast. Most of these were subsequently eroded, leaving only a small area of the Ft. Dodge Gypsum in the north-central part of the state to represent Jurassic surface rocks. This deposit formed when water from the shallow Sundance Sea evaporated, producing an extremely salty solution (a brine). When the solution became sufficiently concentrated, gypsum crystals formed and accumulated on the sea floor." The Jurassic in Iowa

Earliest salamanders, newts - 170 million years ago

First pine trees - 153 million years ago

Cretaceous (145 to 66 million years ago)

10Cretaceous.jpg

Also notable on the Bedrock Geology Map of Iowa is a prominent circular feature, the Manson Meteor Impact Crater (Cretaceous). It is invisible at the land surface because it is buried beneath glacial-age deposits.

"The oldest Cretaceous rocks form the bedrock of northwestern Iowa and originated from sediments deposited in ancient river systems that drained westward to an interior seaway. Floodplains and coastal lowlands were covered with lush subtropical vegetation. Later in the Cretaceous, a vast shallow sea flooded eastward across the state, depositing layers of mud and limy sediments in western Iowa. Bones of large marine reptiles known as plesiosaurs have been found in these rocks. In southwestern Iowa, a fragment of fossil bone recovered from Cretaceous river deposits revealed a microscopic structure very similar to that seen in many dinosaur bones and may represent the first fossil dinosaur material found in the state." The Cretaceous in Iowa

Orb-weaver spiders - 140 million years ago

Earliest bees - 100 million years ago

First ants - 80 million years ago

At the end of the Cretaceous, the Deccan traps and other volcanic eruptions were poisoning the atmosphere. As this continued, it is thought that a large meteor smashed into earth 66 million years ago, creating the Chicxulub Crater in an event known as the K-Pg Extinction (formerly K-T), in which 75% of life became extinct.

Cenozoic Era - 66 Ma – present

"The Age of Mammals" consists of the Paleogene, Neogene and Quaternary Periods.

Paleogene - 66-23.03 million years ago

It features three epochs: the Paleocene, Eocene and Oligocene.

Paleocene epoch lasted from 66 million to 56 million years ago.

Modern placental mammals originated during this time. The Paleocene is a transitional point between the devastation that is the K-T extinction, and the rich jungle environment that is the Early Eocene. The Early Paleocene saw the recovery of the earth. The continents began to take their modern shape, but all the continents and the subcontinent of India were separated from each other. Afro-Eurasia was separated by the Tethys Sea, and the Americas were separated by the strait of Panama, as the isthmus had not yet formed. This epoch featured a general warming trend, with jungles eventually reaching the poles. The oceans were dominated by sharks

Eocene Epoch ranged from 56 million years to 33.9 million years ago.

In the Early-Eocene, species living in dense forest were unable to evolve into larger forms, as in the Paleocene. All known mammals were under 10 kilograms.[13] Among them were early primates, whales and horses along with many other early forms of mammals. At the top of the food chains were huge birds, such as Paracrax. The temperature was 30 degrees Celsius with little temperature gradient from pole to pole. In the Mid-Eocene, the Circumpolar-Antarctic current between Australia and Antarctica formed. This disrupted ocean currents worldwide and as a result caused a global cooling effect, shrinking the jungles. This allowed mammals to grow to mammoth proportions, such as whales which, by that time, had become almost fully aquatic. Mammals like Andrewsarchus were at the top of the food-chain. The Late Eocene saw the rebirth of seasons, which caused the expansion of savanna-like areas, along with the evolution of grass.[14][15] The end of the Eocene was marked by the Eocene-Oligocene extinction event,

  • Modern bird groups diversify (first song birds, parrots, loons, swifts, woodpeckers) - 55 million years ago
  • First bats appear (Onychonycteris) - 52 million years ago
  • Modern-type butterflies and moths appear. - 40 million years ago

Oligocene Epoch spans from 33.9 million to 23.03 million years ago.

The Oligocene featured the expansion of grass which had led to many new species to evolve, including the first elephants, cats, dogs, marsupials and many other species still prevalent today. Many other species of plants evolved in this period too. A cooling period featuring seasonal rains was still in effect.

  • Earliest pigs and cats - 30 million years ago
  • First deer - 25 million years ago
  • Trees representative of most major groups of oaks have appeared - 23 million years ago

Neogene - 23.03-2.58 million years ago

It features 2 epochs: the Miocene, and the Pliocene.

Miocene epoch spans from 23.03 to 5.333 million years ago

Grass spread further, dominating a large portion of the world, at the expense of forests. Kelp forests evolved, encouraging the evolution of new species, such as sea otters. During this time, perissodactyla thrived, and evolved into many different varieties. Apes evolved into 30 species. The Tethys Sea finally closed with the creation of the Arabian Peninsula, leaving only remnants as the Black, Red, Mediterranean and Caspian Seas. This increased aridity. Many new plants evolved: 95% of modern seed plants evolved in the mid-Miocene.

Pliocene epoch lasted from 5.333 to 2.58 million years ago.

The Pliocene featured dramatic climactic changes, which ultimately led to modern species of flora and fauna.

  • The Mediterranean Sea dried up for several million years (because the ice ages reduced sea levels, disconnecting the Atlantic from the Mediterranean, and evaporation rates exceeded inflow from rivers).
  • The isthmus of Panama formed, and animals migrated between North and South America during the great American interchange, wreaking havoc on local ecologies.
  • Climatic changes brought: savannas that are still continuing to spread across the world; Indian monsoons; deserts in central Asia; and the beginnings of the Sahara desert. The world map has not changed much since, save for changes brought about by the glaciations of the Quaternary, such as the Great Lakes, Hudson Bay, and the Baltic sea.

The Great American Interchange

  • where various land and freshwater faunas migrated between North and South America.
  • Armadillos, opossums, hummingbirds Phorusrhacids, Ground Sloths, Glyptodonts, and Meridiungulates traveled to North America
  • Horses, tapirs, saber-toothed cats, Jaguars, Bears, Coaties, Ferrets, Otters, Skunks and deer entered South America.

Glaciation (2.5 million-12,000 years ago)

Quaternary spans from 2.58 million years ago to present day

It is divided into two epochs: the Pleistocene and the Holocene

Pleistocene lasted from 2.58 million to 11,700 years ago.

This epoch was marked by ice ages as a result of the cooling trend that started in the Mid-Eocene. There were at least four separate glaciation periods marked by the advance of ice caps as far south as 40° N in mountainous areas. Many animals evolved including mammoths, giant ground sloths, dire wolves, saber-toothed cats, and most famously Homo sapiens. 100,000 years ago marked the end of one of the worst droughts in Africa, and led to the expansion of primitive humans. As the Pleistocene drew to a close, a major extinction wiped out much of the world's megafauna.

Over Iowa's ancient bedrock lies much younger sediments left by glacial ice, and by the strong winds and swift meltwaters that accompanied the glaciersy. These deposits consist of loose pebbly clay (known as “glacial drift”), silt, sand and gravel.

Landforms of Iowa Map

Glaciers originated in the Canadian arctic and advanced over all or parts of Iowa numerous times between 2.6 million and 10,000 years ago. Iowa’s oldest glacial deposits are more than 500,000 years old and are seen across the Southern Iowa Drift Plain that covers the southern third of the state with rolling hills and well drained landscapes showing the long-term effects of stream erosion.

Between about 30,000 and 14,000 years ago, Iowa was free of ice, but the glaciers lay close by to the north. Summer melting carried glacial debris down meltwater rivers, especially the Missouri. During winter periods of low flow, strong westerly winds carried silt from the broad floodplain, and draped a gritty blanket of “loess” across most of Iowa. These deposits are especially thick along the eastern margins of the Missouri Valley. Later erosion of this silt gave rise to the unique, sharply ridged topography of western Iowa’s Loess Hills region.

During an especially intense period of glacial cold, between 21,000 and 16,000 years ago, the ice-free landscapes across northern Iowa were exposed to tundra-like conditions, with seasonal freezing and thawing of permafrost in the ground. These erosion cycles leveled out the once hilly terrain creating the more gently rolling landscapes of both the Iowan Surface (north-central to northeast Iowa) and Northwest Iowa Plains regions. The Iowan Surface in particular displays an unusual number of glacial boulders - called “erratics” - left concentrated at the land surface.

Then came a final surge of glacial ice into north-central Iowa, even as the overall climate was moderating. This ice advance is known as the Des Moines Lobe, named for the city that now sits at the southernmost reach of the glacier. These are Iowa’s freshest glacial deposits (only 15,000 to 12,000 years old), and they contrast sharply with the rest of the state. This distinctive landscape still shows the imprints of a slowly stagnating glacier – poorly drained, with numerous wetlands, lakes, and ridges called “moraines.”

Cerro Gordo county is divided almost exactly down the middle between the Des Moines Lobe on the west, and the Iowan Surface on the East. Pilot Knob State Park is located on a morraine or glacial ridge of the Des Moines Lobe.

Fascinating fossils from Ice Age deposits in Iowa range from mammoths, mastodons, giant sloths, musk-ox and caribou; to smaller Arctic fox, shrews and lemmings; to tiny snails, insects and fossil pollen grains.

All recorded history and "the history of the world" lies within the Holocene epoch

Paleoindian

The Paleoindian period in North America dates to about 9,500-7,500 B.C. Paleoindians in Iowa encountered vastly different environments than those of the recent past. The climate was cooler and wetter than present averages. In north central Iowa, Paleoindians lived in recently deglaciated landscapes covered by boreal and conifer-hardwood forests, shifting through time to elm- and oak- dominated woodlands. Woodlands predominated in most of the state as well, and prairie, if present, was very limited.

The Clovis complex is the earliest well defined archaeological culture currently known in North America. Clovis and other fluted projectile point styles were made during the first two-thirds of the Paleoindian period, and Dalton and unfluted point forms date to the latter one-third of the period. Aside from these lanceolate (lance-shaped) points, defining characteristics of the Paleo-Indian period include distinctive butchering tools, extensive use of exotic chert types, and specialized lithic technologies. Fluted and unfluted point forms have been recovered as surface finds from upland and valley locations throughout Iowa.

Paleoindian peoples were extremely mobile, hunting various animals including now-extinct large mammals such as mammoth, mastodon, and giant bison. Most Paleoindian sites so far located in the United States are large mammal kill sites, and little is known of other site types. No Paleoindian base camps have yet been documented in Iowa. To date, the best documented fluted point site in Iowa is a plow-disturbed cache of Clovis points known as the Rummells-Maske site in Cedar County.

Archaic

The Early Archaic period (7,500-5,500 B.C.) is viewed as a somewhat transitional period between cultures relying on big game for subsistence and those with a more rounded forager adaptation. Environments changed relatively quickly, as deciduous woodlands, mixed with prairies in western areas, became established over most of the state. Populations probably depended on bison in western Iowa and on deer and elk in eastern Iowa. These large mammals were supplemented by smaller game and by increasing use of plant foods. Settlement types included somewhat permanent base camps and seasonally occupied resource procurement camps. Excavated sites, such as the Cherokee Sewer site, suggest local populations were small and that they were tied to a seasonal round of resource exploitation. Representative artifacts include medium to large spear points, often with serrated and beveled blade edges.

The Middle Archaic period (5,500-2,500 B.C.) is so poorly known in Iowa that it has normally been lumped with the Early Archaic. Cultural adaptations may have been similar, but environmental conditions became increasingly arid throughout the period. The Middle Archaic period corresponds to the warmest and driest postglacial period, commonly referred to as the Atlantic episode, or the Hypsithermal. Human populations throughout the Midwest gravitated to the wetter river valleys, and because of this, Middle Archaic sites are often deeply buried and difficult to locate. During the Hypsithermal, great masses of silt filled river valleys, and alluvial fan development was rapid. Many Middle Archaic sites are buried in these alluvial sediments.

By the Late Archaic period (2,500-500 B.C.) the Midwest was becoming a fairly crowded place with the incidence of intergroup encounter rising sharply. This situation resulted in similar subsistence strategies over broad areas, but also in increased territoriality, local differentiation in artifact styles, and development of intergroup trading networks. The end of the dry Hypsithermal resulted in increased stability of the resource base and made many previously unsuitable areas attractive for settlement. Population levels appear to have increased substantially, and a somewhat sedentary lifeway as well as construction of large ossuaries (multiple-interment cemeteries) are documented for this period. The use of communal cemeteries reinforces the interpretation that populations were becoming more sedentary.

Woodland

The Woodland tradition (500 B.C.-A.D. 1000) was characterized by improved technologies, such as ceramic production and horticulture, leading to an overall increase in productive efficiency, and by the construction of burial mounds. Although these characteristics originated during the Archaic, only after 500 B.C. did they come together and become adopted over a wide area.

Woodland peoples refined their hunter-gatherer adaptations, making heavy use of fish and clams in majorriver valleys, and continuing to exploit deer and bison. Dependence on cultivated plants increased. Native plants often thought of as weeds today were grown for their nutritious seeds. Woodland farmers developed domesticated varieties of some of these native grain crops long before corn or beans became important. Climatic conditions approached modern averages, landform development stabilized in most places except in flood plains and stream channels, and vegetation patterns were much like the forest-prairie mix documented by nineteenth-century land surveys.

Early Woodland settlements (500-100 B.C.) in the Midwest were small and seasonally occupied. Early Woodland subsistence patterns in Iowa are not well known, but they probably involved broad-based procurement of mammals, birds, and aquatic species. Early Woodland peoples built large burial mounds similar to some in Ohio, and they interacted with groups throughout the Midwest, as evidenced by artifacts made of exotic raw materials. The typical Early Woodland spear point was a straight stemmed or contracting stemmed point, and pottery of the period includes both a thick, flat- bottomed type (500-300 B.C.) and a thinner, bag-shaped type often decorated with incised lines in geometric patterns (300-100 B.C.). Early Woodland sites are relatively common in the Mississippi Valley but are difficult to identify in central and western Iowa. Perhaps groups on the eastern Great Plains retained an Archaic lifestyle during this period.

The Middle Woodland period (100 B.C.-A.D. 300) is noted for its refined artworks, complex mortuary program, and extensive trade networks. Middle Woodland communities throughout the Midwest were linked by a network archaeologists refer to as the Hopewell Interaction Sphere. Trading involved materials such as Knife River flint from North Dakota and obsidian from the Yellowstone Park area. Also exchanged through the Hopewell network were artifacts of marine shell, copper, mica, and several pipestones, as well as high quality ceramic vessels and possibly perishable materials which have not survived archaeologically. Elaboration of the mortuary program and social stratification indicate increased levels of social and political complexity. However, most Middle Woodland peoples probably lived in small communities or farmsteads, focusing their subsistence economy on food resources in large river valleys and tending gardens of squash, tobacco, and native grain crops such as marshelder and goosefoot. Typical Middle Woodland tools included broad, corner-notched spear points and finely made, thin blades.

By Late Woodland times (A.D. 300-1000) the continent-wide exchange of exotic goods declined but interaction between communities and tribes continued. Population levels apparently increased rapidly. In some parts of Iowa, Late Woodland peoples aggregated into large, planned villages, but in most of the state settlements continued to be small and generally became more dispersed across the landscape. Uplands and small interior valleys became settled or more heavily utilized. Late Woodland peoples introduced the bow and arrow into the Midwest. Continued native crop horticulture and diversified hunting and gathering provided the subsistence base through most of the period. Corn was introduced to many groups after around A.D. 800 but did not form a staple crop until the Late Prehistoric period.

Mound construction was generally simpler than in the Middle Woodland period, but regular aggregations for ritual and other purposes are probably reflected in the Late Woodland mound groups found throughout the state. Groups of linear, effigy, and conical mounds in northeastern Iowa form a distinctive element of the Effigy Mound Culture (A.D. 650-1000). The living sites of Effigy Mound peoples show a seasonal settlement pattern involving fish and shellfish collection during warm seasons in the main river valleys, nut harvesting in uplands in the fall, and winter use of rockshelters. Effigy Mound populations may have lived in dispersed groups in the interior of northeast Iowa during much of the year, coalescing regularly in the Mississippi valley to exploit the vast array of seasonally available resources. The effigy mound groups along the Mississippi bluff line may have signified the territories of loosely related nuclear or extended family units which met seasonally and merged into a larger social unit.

Late Prehistoric

The Plains Village pattern appeared in Late Prehistoric times (A.D. 1000-1650) marking the beginning of a distinctive adaptation to the tall grass prairie/short grass plains ecotone of South Dakota, Nebraska, western Iowa, and southern Minnesota. Improved corn varieties, garden surpluses, new storage methods, earthlodge houses, and a complex social organization were common to these Late Prehistoric villagers. Bison meat was a common item in the diet, and hides were processed for clothing, robes, and coverings for tipis and lodges. Bison bones were modified into a variety of tools such as scapula hoes, used in gardening and digging.

One of the earliest of the Plains Village cultures was Great Oasis. Great Oasis culture developed from the local Late Woodland culture around A.D. 1000. Great Oasis sites are found over a wide area in the eastern Great Plains. Villages were situated on low terraces above the flood plains of rivers and streams, and on lake shores. Large, permanent villages may have been occupied by the entire popu lation throughout the fall, winter, and spring. Smaller, temporary campsites were used for seasonal procurement of resources. During the summer a communal bison hunt or the establishment of small campsites for horticultural purposes may have led to temporary abandonment of the large settlements.

Mill Creek, a northwest Iowa culture of this period, is part of what prehistorians refer to as the Initial variant of the Middle Missouri tradition. Mill Creek villages appear as deep midden deposits on terraces above the Big and Little Sioux rivers and their tributaries. Many of the well planned, compact villages were fortified with log palisades, and encircling ditches. Within the villages were individual earthlodges with large internal storage pits. Mill Creek people were semisedentary horticulturalists who grew a large amount of corn along with the native crops, possibly using ridged-field agriculture. It is likely that, as with other Plains Village groups, a communal bison hunt was conducted on one or more occasions during the year. Mill Creek people maintained connections, possibly through trade, with major prehistoric centers in the Mississippi valley, such as the famous site of Cahokia near St. Louis.

The Central Plains tradition consisted of cultures in Kansas, Nebraska, western Missouri, and southwestern Iowa. Many Central Plains sites were settled farming communities whose residents built substantial earthlodge houses. The archaeological remains of communities along the Missouri River in eastern Nebraska, southwestern Iowa, northwestern Missouri, and northeastern Kansas are grouped into what is called the Nebraska phase. Any relationships between the prehistoric Nebraska phase and historic tribes are unclear, although the historic Pawnee may have roots in the Central Plains tradition. Over 80 Central Plains earthlodges have been recorded in the Glenwood locality, Mills County. They represent a fully-developed expansion of Nebraska phase people into southwestern Iowa around A.D. 1050-1250. Glenwood settlements were individual farmsteads or small clusters of earthlodges dispersed along ridge summits, low terraces, and valley wall slopes in the Loess Hills and adjacent landforms.

During the Late Prehistoric period the Oneota culture dominated much of eastern Iowa as well as extensive parts of central and northwestern Iowa. Oneota peoples lived throughout the Midwest between around A.D. 1050 and 1700. Oneota villages were large and permanent or semipermanent. Houses varied in form from small, square or oval single-family dwellings to longhouses with many families. The subsistence economy was based on fishing, hunting, plant collecting, and agriculture. Distinct Oneota groups occupied widely separated regions of Iowa. Each group, or phase, occupied a core locality where villages were densely packed on the landscape. These core areas are surrounded by huge territories that were probably used for hunting, gathering, and other resource procurement. Although the various phases appear to have been generally autonomous, there was probably a great deal of interaction and socio-political cohesion among them. Oneota complexes are ancestral to several midwestern tribes such as the Iowa, Oto, Missouri, and Winnebago.

Historic Indians and Euro-Americans

Several Oneota sites in northeastern and northwestern Iowa bridge the prehistoric and historic eras (A.D. 1640-1700). Early French trade goods such as glass beads, finger rings, and gunflints are found at sites dominated by native-made material. In Iowa the term "protohistoric denotes this period, when European goods were arriving and other influences were felt but before European peoples started to make extensive written records of the area.

Indian groups residing in or using portions of Iowa seasonally in protohistoric times included the Iowa, Oto, Omaha, perhaps the Missouri, and the Middle and Eastern Dakota. These groups were essentially sedentary, but elements of their populations made wide-ranging seasonal forays for hunting and warfare.

After around 1650, European competition for tribal alliances and trade, and European diseases, drastically changed the structure of and relationships among Indian groups. Tribal population declined and white dispossession of traditional territories became common. In Iowa, the tribes mentioned above gave way to Great Lakes groups including the Sauk, Mesquakie (Fox), Winnebago, and Potawatomi. Perhaps the best known of these groups among Iowans is the Mesquakie.

The name Mesquakie means "people of the red earth." Oral history indicates a tribal origin in the lower Great Lakes. At the time of earliest French contact, the Mesquakies had recently moved from Michigan to Wisconsin. In the early 1700s French pressure forced the tribe into Illinois. By 1750, the Mesquakies considered Iowa their homeland, and they established priority rights to the Iowa River valley by 1800. Further pressured by white incursion into Iowa, the Mesquakies ceded Iowa lands in 1804, 1832, 1836, 1837, and 1842. Most Mesquakie people continued to live in villages in the Iowa River valley, moving farther up river with each land cession. Some Mesquakies remained in Iowa even after the "official" removal of Indians from Iowa in 1845. In the 1850s, the Mesquakies residing in Iowa and those returning from western reservations purchased land in Tama County, and the Mesquakie settlement was legally founded.

European-sponsored enterprises affecting Iowa in the early Historic period included the fur trade and, in northeastern Iowa, lead mining. In 1762, the area that is now Iowa came under Spanish rule. The Mines of Spain State Recreation Area, Dubuque County, is a portion of Julien Dubuque's original land grant which he received from the Spanish government in 1796. The Mesquakie Indians, who moved into the area in the mid-1770s, allowed Dubuque to mine for lead in what they considered their territory from 1788 to Dubuque's death in 1810. Two other Spanish land grants were given to private individuals-one to Basil Giard in what is now Clayton County and one to Louis Tesson in what is now Lee County. The United States obtained Iowa as part of the Louisiana Purchase in 1803, and soon thereafter President Jefferson sent Lewis and Clark to explore the Louisiana Purchase. They traveled up the Missouri River in 1804, meeting with the Oto and Missouri tribes and hunting in the Loess Hills. In 1809, Fort Madison was built, followed by Fort Armstrong at Rock Island, Fort Crawford at Prairie du Chien, and Fort Atkinson in Winneshiek County. In 1833, much of eastern Iowa was opened for non-Indian settlement and by 1850, small towns were scattered across the state. Early settlements were along rivers, especially in eastern Iowa. By 1870 railroads had spread across the state, and river transportation declined in importance.

Most of Iowa's cities and towns were established by the mid-1800s. Farms covered the state, and industries such as coal mining flourished. By the time of statehood in 1846, the character of modern Iowa had been formed by events of its most recent history.

Duncan Rule House National Register Application
The house was designed by E.R. Bogardus (1850-1927), a long-time resident and builder in Mason City. Bogardus came to Mason City as a child. He opened a contracting business in 1873. Although he apparently had no formal architectural training, he gradually began to design, as well as construct, houses, and after 1894 devoted all his time to architecture. During his long career, Bogardus was responsible for numerous buildings in Mason City. His works included the mission-style Calvary M.E. Church (1913); the Georgian/Federal Revival Verimlya (1894), (house next door, related to E.R. Bogardus’ mother) Markley (c. 1902), and Keerl (c. 1894) houses; the City Park Hospital (1909), and the Queen Anne Longenecker house (1898), as well as assorted commercial buildings. He designed two houses using elements of the Shingle idiom: the Duncan Rule house and its precursor, the George Wilson house (1907).... http://focus.nps.gov/pdfhost/docs/NRHP/Text/79000886.pdf
