Eel River (Wabash River)
The Eel River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map , accessed May 19, 2011 tributary of the Wabash River in northern Indiana in the United States. Via the Wabash and Ohio rivers, its waters flow to the Mississippi River and ultimately the Gulf of Mexico. The Eel River rises southeast of Huntertown in Allen County and flows southwest through Allen, Whitley, Kosciusko, Wabash, Miami, and Cass counties to join the Wabash at Logansport. The river was called Kineepikwameekwa Siipiiwi - "river of the snake fish" by the Miami people, who inhabited the area at the time of European contact, the English rendered it as ''Ke-na-po-co-mo-co''. It is the northern of the two rivers named Eel River within Indiana. Origins and history Natural history Originating as an "ice-marginal channel" at the edge of the retreating Saginaw Lobe of the Wisconsin Glacier, the Eel River was later buried by the glacier's advancing Erie ...

Saginaw Lobe
The Wisconsin glaciation, also called the Wisconsin glacial episode, was the most recent glacial period of the North American ice sheet complex, peaking more than 20,000 years ago. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the ''Late Wisconsin'' in North America. This glaciation ra ...

Prehistoric
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Indigenous Peoples
There is no generally accepted definition of Indigenous peoples, although in the 21st century the focus has been on self-identification, cultural difference from other groups in a state, a special relationship with their traditional territory, and an experience of subjugation and discrimination under a dominant cultural model. Estimates of the population of Indigenous peoples range from 250 million to 600 million. There are some 5,000 distinct Indigenous peoples spread across every inhabited climate zone and inhabited continent of the world. Most Indigenous peoples are in a minority in the state or traditional territory they inhabit and have experienced domination by other groups, especially non-Indigenous peoples. Although many Indigenous peoples have experienced colonization by settlers from European nations, Indigenous identity is not determined by Western colonization. The rights of Indigenous peoples are outlined in national legislation, treaties and international law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Maumee River
The Maumee River (pronounced ) (; ) is a river running in the Midwestern United States from northeastern Indiana into northwestern Ohio and Lake Erie. It is formed at the confluence of the St. Joseph River (Maumee River), St. Joseph and St. Marys River (Indiana), St. Marys rivers, where Fort Wayne, Indiana, has developed, and meanders northeastwardly for U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed May 19, 2011 through an agriculture, agricultural region of glacial moraines before flowing into the Maumee Bay of Lake Erie. The city of Toledo, Ohio, Toledo is located at the mouth of the Maumee. The Maumee was designated an Ohio State Scenic River on July 18, 1974. The Maumee watershed is Ohio's breadbasket; it is two-thirds farmland, mostly corn and soybeans. It is the largest watershed of any of the rivers feeding the Great Lakes, and supplies five percent of Lake Erie's water. History Historically the river ...

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Stream Capture
Stream capture, river capture, river piracy or stream piracy is a geomorphological phenomenon occurring when a stream or river drainage system or watershed is diverted from its own bed, and flows down to the bed of a neighbouring stream. This can happen for several reasons, including: *Tectonic earth movements, where the slope of the land changes, and the stream is tipped out of its former course *Natural damming, such as by a landslide or ice sheet *Erosion, either ** Headward erosion of one stream valley upwards into another, or **Lateral erosion of a meander through the higher ground dividing the adjacent streams. **Within an area of karst topography, where streams may ''sink'', or flow underground (a sinking or losing stream) and then reappear in a nearby stream valley *Glacier retreat The cause is not always clear. The additional water flowing down the capturing stream may accelerate erosion and encourage the development of a canyon (gorge). The now-dry valley of the o ...

Outwash Fan
An outwash fan is a fan-shaped body of sediments deposited by braided streams from a melting glacier. Sediment locked within the ice of the glacier gets transported by the streams of meltwater, and deposits on the outwash plain, at the terminus of the glacier. The outwash, the sediment transported and deposited by the meltwater and that makes up the fan, is usually poorly sorted due to the short distance traveled before being deposited. Formation Outwash fans typically form from valley glaciers flowing downhill in the mountains. Thus, outwash fans are usually found in colder environments where glaciers are more prevalent and are often located where a valley or canyon empties out onto a flatter wider plain. Outwash fans form when melt-water from a retreating glacier deposits transported sediment in the shape of a fan along the outwash plain. Glaciers contain large amounts of sediment (i.e. sand, silt, clay) that is gathered through glacial erosional processes such as abrasio ...

Cedar Creek Canyon (Indiana)
Cedar Creek Canyon, also called simply Cedar Canyon, is a topographical feature located in Allen County, Indiana, United States. It is a very straight, narrow gorge about deep that contains part of the lower segment of Cedar Creek, the largest tributary of the St. Joseph River. The canyon originated at the end of the last ice age as a tunnel valley, a channel under the Erie Lobe of the Wisconsin Glacier that discharged meltwater under considerable pressure into the ancestral Eel River, a tributary of the Wabash River. Cutting through the north limb of the Wabash Moraine, a debris deposit left by the retreating ice, the discharge left a large outwash fan that blocked the Eel, diverting its upper portion into the canyon in a classic example of stream piracy that formed today's Cedar Creek. This was part of a general drainage reversal that occurred in northeastern Indiana as the Maumee River opened and captured drainage that was previously part of the watershed of the Wab ...

Ancestor
An ancestor, also known as a forefather, fore-elder, or a forebear, is a parent or ( recursively) the parent of an antecedent (i.e., a grandparent, great-grandparent, great-great-grandparent and so forth). ''Ancestor'' is "any person from whom one is descended. In law, the person from whom an estate has been inherited." Relationship Two individuals have a genetic relationship if one is the ancestor of the other or if they share a common ancestor. In evolutionary theory, species which share an evolutionary ancestor are said to be of common descent. However, this concept of ancestry does not apply to some bacteria and other organisms capable of horizontal gene transfer. Some research suggests that the average person has twice as many female ancestors as male ancestors. This might have been due to the past prevalence of polygynous relations and female hypergamy. Assuming that all of an individual's ancestors are otherwise unrelated to each other, that individual has 2'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
DeKalb County, Indiana
DeKalb County is a county in the U.S. state of Indiana. As of the 2020 United States Census, the population was 43,265. The county seat is Auburn. History On February 7, 1835, the Indiana State Legislature passed an omnibus bill that authorized the creation of thirteen counties in northeast Indiana on previously unorganized land (including the recent Wabash New Purchase). The organization of the county's government commenced in 1837. It was named for General Johann de Kalb, a Continental Army officer from Bavaria, who was killed at the Battle of Camden in South Carolina. The first settlers in the future DeKalb County were from New England, settling what was then known as the Northwest Territory. These people were "Yankee" migrants, descended from the English Puritans who settled New England in the colonial era. In the 1870s immigrants from Ireland and Germany began arriving in DeKalb County, in large numbers. Geography DeKalb County lies on the east side of Indiana; its e ...
