History Of The Indiana Dunes
The Indiana Dunes are natural sand dunes occurring at the southern end of Lake Michigan in the American State of Indiana. They are known for their ecological significance.Smith, S. & Mark, S. (2009). The Historical Roots of the Nature Conservancy in the Northwest Indiana/Chicagoland Region: From Science to Preservation. The South Shore Journal, 3. Many conservationists have played a role in preserving parts of the Indiana Dunes. The Hour Glass, a museum in Ogden Dunes, showcases some of the ecological import of the Dunes. Human presences in the Indiana Dunes have existed since the retreat of the glaciers some 14,000 years ago. The southern lakes area was a rich hunting ground and there is little evidence of permanent communities forming during the earlier years. Archeological evidence is consistent with seasonal hunting camps. The earliest evidence for permanent camps is consistent with the Hopewellian occupation of the Ohio valley. Five groups of mounds have been documented in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Dunes
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented san ...

Blowout (geology)
Blowouts are sandy depressions in a sand dune ecosystem (psammosere) caused by the removal of sediments by wind. Commonly found in coastal settings and margins of arid areas, blowouts tend to form when wind erodes patches of bare sand on stabilized vegetated dunes. Generally, blowouts do not form on actively flowing dunes due to the fact that the dunes need to be bound to some extent, for instance by plant roots. These depressions usually start on the higher parts of stabilized dunes on account of the more considerable desiccation and disturbances occurring there, which allows for greater surface drag and sediment entrainment when the sand is bare. Most of the time, exposed areas become quickly re-vegetated before they can become blowouts and expand; however, when circumstances are favourable, wind erosion can gouge the exposed surface and create a tunneling effect which increases local wind speed. A depression may then develop until it hits a non-erodible substrate, or morphol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adena Culture
The Adena culture was a Pre-Columbian Native American culture that existed from 500 BCE to 100 CE, in a time known as the Early Woodland period. The Adena culture refers to what were probably a number of related Native American societies sharing a burial complex and ceremonial system. The Adena culture was centered on the location of the modern state of Ohio, but also extended into contiguous areas of northern Kentucky, eastern Indiana, West Virginia, and parts of extreme western Pennsylvania. Importance The Adena culture was named for the large mound on Thomas Worthington's early 19th-century estate located near Chillicothe, Ohio, which he named "Adena", The culture is the most prominently known of a number of similar cultures in eastern North America that began mound building ceremonialism at the end of the Archaic period. The geographic range of the Adena sites is centered on central and southern Ohio, with further sites in contiguous areas of the surrounding states of Indi ...

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. ...

Old Copper Complex
The Old Copper complex or Old Copper culture is an archaeological culture from the Archaic period of North America's Great Lakes region. Artifacts from some of these sites have been dated from 7500 to 1000 BCE. It is characterized by widespread copper artifacts, including tools and weapons, as well as ornamental objects. The archeological evidence of smelting or alloying is subject to some dispute, and it is commonly believed that objects were cold-worked into shape. Furthermore, some archaeologists are convinced by the artifactual and structural evidence for metal casting by Hopewellian and Mississippian peoples. Western Great Lakes The Old Copper Complex of the Western Great Lakes is the best known, and can be dated as far back as 9,500 years ago. Great Lakes natives of the Archaic tradition located 99% pure copper near Lake Superior, in veins touching the surface and in nuggets from gravel beds. Major quarries were located on Isle Royale, the Keweenaw Peninsula, and the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Clovis Culture
The Clovis culture is a prehistoric Paleoamerican culture, named for distinct stone and bone tools found in close association with Pleistocene fauna, particularly two mammoths, at Blackwater Locality No. 1 near Clovis, New Mexico, in 1936 and 1937 (though Paleoindian artifacts had been found at the site since the 1920s). It appears around 11,500–11,000 uncalibrated years before present (YBP)"Clovis Culture" entry in the ''Concise Oxford Dictionary of Archaeology'': "9,500–9,000 BC". at the end of the last glacial period and is characterized by the manufacture of " Clovis points" and distinctive bone and ivory tools. Archaeologists' most precise determinations at present suggest this radiocarbon age is equal to roughly 13,200 to 12,900 calendar years ago. The only human burial that has been directly associated with tools from the Clovis culture included the remains of an infant boy researchers named Anzick-1.

Helen Hornbeck Tanner
Helen Hornbeck Tanner (1916–2011) was an American advocate of Native American rights and a historian. She argued for Native Americans in court cases, and she documented the tribes of the Great Lakes in 1987. Tanner was inducted into the Michigan Women's Hall of Fame in 2006. Personal life and education Tanner was born on July 5, 1916, in Northfield, Minnesota. She spent most of her childhood in Kalamazoo, Michigan. She graduated from Swarthmore College in 1937 with honors. Tanner earned a master's degree from the University of Florida in 1948. She married the psychologist Wilson Tanner in 1940 and they had four children. While living in Ann Arbor, Michigan, Tanner earned a PhD in history from the University of Michigan in 1961. Tanner started studying the history of Native Americans in the early 1960s when she read tribe maps that had "insufficient data" or "unknown tribes". Career Beginning in 1962, Tanner was a part of 16 Indian Claims Commission cases as an expert wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio River Valley
The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States. It is also the 6th oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the elevation falls in restricting larger commercial navigation, although in the 18th a ...

Fort Ancient
Fort Ancient is a name for a Native American culture that flourished from Ca. 1000-1750 CE and predominantly inhabited land near the Ohio River valley in the areas of modern-day southern Ohio, northern Kentucky, southeastern Indiana and western West Virginia. Although a contemporary of the Mississippian culture, they are often considered a "sister culture" and distinguished from the Mississippian culture. Although far from agreed upon, there is evidence to suggest that the Fort Ancient Culture were not the direct descendants of the Hopewellian Culture. It is suspected that the Fort Ancient Culture introduced maize agriculture to Ohio. The Fort Ancient Culture were most likely the builders of the Great Serpent Mound. Name The name of the culture originates from the Fort Ancient, Ohio archeological site. However, the Fort Ancient Site is now thought to have been built by Ohio Hopewellian people. It was likely occupied later by the succeeding Fort Ancient culture. The site is loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
