Driftless Area
The Driftless Area, a topographical and cultural region in the American Midwest, comprises southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois. Never covered by ice during the last ice age, the area lacks the characteristic glacial deposits known as drift. Its landscape is characterized by steep hills, forested ridges, deeply carved river valleys, and karst geology with spring-fed waterfalls and cold-water trout streams. Ecologically, the Driftless Area's flora and fauna are more closely related to those of the Great Lakes region and New England than those of the broader Midwest and central Plains regions. The steep riverine landscape of both the Driftless Area proper and the surrounding Driftless-like region are the result of early glacial advances that forced preglacial rivers that flowed into the Great Lakes southward, causing them to carve a gorge across bedrock cuestas, thereby forming the modern incised upper Mi ...

Iowa
Iowa () is a state in the Midwestern region of the United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River to the west. It is bordered by six states: Wisconsin to the northeast, Illinois to the east and southeast, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north. During the 18th and early 19th centuries, Iowa was a part of French Louisiana and Spanish Louisiana; its state flag is patterned after the flag of France. After the Louisiana Purchase, people laid the foundation for an agriculture-based economy in the heart of the Corn Belt. In the latter half of the 20th century, Iowa's agricultural economy transitioned to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production. Iowa is the 26th most extensive in total area and the 31st most populous of the 50 U.S. states, with a populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Mississippi River
The Upper Mississippi River is the portion of the Mississippi River upstream of St. Louis, Missouri, United States, at the confluence of its main tributary, the Missouri River. History In terms of geologic and hydrographic history, the Upper Mississippi east and south of Fort Snelling is a portion of the now-extinct Glacial River Warren which carved the valley of the Minnesota River, permitting the immense Glacial Lake Agassiz to join the world's oceans at the Gulf of Mexico. The collapse of ice dams holding back Glacial Lake Duluth and Glacial Lake Grantsburg carved out the Dalles of the St. Croix River at Interstate Park. The Upper Mississippi River valley likely originated as an ice-marginal stream during the Pre-Illinoian Stage. The Driftless Area is a portion of North America left unglaciated at that ice age's height, hence not smoothed out or covered over by previous geological processes. Inasmuch as the Wisconsin glaciation formed lobes that met (and blocked) wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mound Builder (people)
A number of pre-Columbian cultures are collectively termed "Mound Builders". The term does not refer to a specific people or archaeological culture, but refers to the characteristic mound earthworks erected for an extended period of more than 5,000 years. The "Mound Builder" cultures span the period of roughly 3500 BCE (the construction of Watson Brake) to the 16th century CE, including the Archaic period, Woodland period ( Calusa culture, Adena and Hopewell cultures), and Mississippian period. Geographically, the cultures were present in the region of the Great Lakes, the Ohio River Valley, and the Mississippi River valley and its tributary waters. The first mound building was an early marker of political and social complexity among the cultures in the Eastern United States. Watson Brake in Louisiana, constructed about 3500 BCE during the Middle Archaic period, is currently the oldest known and dated mound complex in North America. It is one of 11 mound complexes from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland Period
In the classification of :category:Archaeological cultures of North America, archaeological cultures of North America, the Woodland period of North American pre-Columbian cultures spanned a period from roughly 1000 Common Era, BCE to European contact in the eastern part of North America, with some archaeologists distinguishing the Mississippian period, from 1000 CE to European contact as a separate period. The term "Woodland Period" was introduced in the 1930s as a generic term for prehistoric, prehistoric sites falling between the Archaic period in the Americas, Archaic hunter-gatherers and the agriculturalist Mississippian cultures. The Eastern Woodlands cultural region covers what is now eastern Canada south of the Subarctic region, the Eastern United States, along to the Gulf of Mexico. This period is variously considered a developmental stage, a time period, a suite of technological adaptations or "traits", and a "family tree" of cultures related to earlier Archaic cultures. ...

Oneota
Oneota is a designation archaeologists use to refer to a cultural complex that existed in the eastern plains and Great Lakes area of what is now occupied by the United States from around AD 900 to around 1650 or 1700. Based on classification defined in Gordon Willey and Philip Phillips' 1958 book ''Method and Theory in American Archaeology'', the Oneota culture belongs to formative stage. The culture is believed to have transitioned into various Siouan cultures of the protohistoric and historic times, such as the Ioway. A long-accepted ancestry to the Ho-chunk has yet to be conclusively demonstrated. Oneota is considered a major component of Upper Mississippian culture. It is characterized by globular, shell-tempered pottery that is often coarse in fibre. Pieces often had a spherical body, short necks and/or a flat lip. Sometimes the vessels had strap handles. Decoration includes wavy and zigzag lines, often in parallel. Most decoration was done on the top half of the ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cahokia
The Cahokia Mounds State Historic Site ( 11 MS 2) is the site of a pre-Columbian Native American city (which existed 1050–1350 CE) directly across the Mississippi River from modern St. Louis, Missouri. This historic park lies in south-western Illinois between East St. Louis and Collinsville. The park covers , or about , and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about and included about 120 earthworks in a wide range of sizes, shapes, and functions."Nomination – Cahokia Mounds State Historic Site, Illinois" ''US World Heritage Sites'', National Park Service, accessed 2012-05-03 Cahokia was the largest and most influential urban settlement of the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthwork (archaeology)
In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks can themselves be archaeological features, or they can show features beneath the surface. Types Earthworks of interest to archaeologists include hill forts, henges, mounds, platform mounds, effigy mounds, enclosures, long barrows, tumuli, ridge and furrow, mottes, round barrows, and other tombs. * Hill forts, a type of fort made out of mostly earth and other natural materials including sand, straw, and water, were built as early as the late Stone Age and were built more frequently during the Bronze Age and Iron Age as a means of protection. See also Oppidum. * Henge earthworks are those that consist of a flat area of earth in a circular shape that are encircled by a ditch, or several circular ditches, with a bank on the outside of the ditch built with the earth from inside the ditch. They are believed to have been used as monum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
