East Savanna River
The East Savanna River is a small yet historic stream in Aitkin and Saint Louis counties in the U.S. state of Minnesota. With a total length of ,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map , accessed May 7, 2012 the river rises in Wolf Lake, a small body of water within a spruce bog in Savanna Portage State Park, and flows northeasterly to the Saint Louis River at Floodwood, whence its waters flow to Lake Superior through the Great Lakes and the Saint Lawrence River to the Atlantic Ocean. A few thousand years ago the East Savanna was part of the Mississippi River itself, originating in northeast Minnesota and flowing southwesterly to Big Sandy Lake, from which the great river drained down its present valley to the Gulf of Mexico. The low divide which now separates the Mississippi tributaries from the East Savanna was part of a historic trade route connecting the Saint Lawrence and Great Lakes to the Mississippi basin ...

Aitkin County
Aitkin County ( ) is a county in the U.S. state of Minnesota. As of the 2020 census, the population was 15,697. Its county seat is Aitkin. Part of the Mille Lacs Indian Reservation is in the county. The county was created in 1857 and organized in 1871. History Aitkin County was established in 1857 as ''Aiken County''. The current spelling was adopted in 1872. It was named for William Alexander Aitken, a fur trader for the American Fur Company, under John Jacob Astor. Formed from Ramsey and Pine counties, Aiken County originally consisted of the 17 townships closest to Mille Lacs Lake. It acquired outlands of Ramsey, Itasca and Pine Counties to its north and east.

Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Laurentian Mixed Forest Province
The Laurentian Mixed Forest Province, also known as the North Woods, is a forested ecoregion in eastern North America. Among others, this terminology has been adopted by the Minnesota Department of Natural Resources. Similar, though not necessarily entirely identical regions, are identified by the United States Environmental Protection Agency as Northern Lakes and Forests, and by the World Wildlife Fund by regions such as the Western Great Lakes forests and Eastern forest-boreal transition. Geography In the United States, it consists of a broad region of northern Minnesota, Wisconsin and Michigan (Northern Michigan and the Upper Peninsula) and the forested areas of the North Country (New York) and New England. In Canada, it is found in Ontario around the Great Lakes and the Saint Lawrence River through Quebec to Quebec City. Nearly all of the region was covered by glaciers during the last ice age, which created many lakes and wetlands throughout the region. The poor soi ...

Lacustrine Plain
A lacustrine plain or lake plain is a plain formed due to the past existence of a lake and its accompanying sediment accumulation. Lacustrine plains can be formed through one of three major mechanisms: glacial drainage, differential uplift, and inland lake creation and drainage. Lake plains can have various uses depending on where and how they form. Over time, in regions where a lake once existed, as water drains or evaporates from the lake, the deposited sediments are left behind, resulting in a level plain of land where the lake once existed. The soil of the plain may constitute fertile and productive farmland due to the previous accumulation of lacustrine sediments; in other cases, it may become a wetland or a desert. Background Lacustrine plains are plains formed when lakes filled with sediments are drained. There are several reasons why drainage might occur, but in all cases the water in the lake is lost, leaving behind a level land of sediments. The resulting plain is an a ...

Charles Kenneth Leith
Charles Kenneth Leith (January 20, 1875 – September 13, 1956) was an American geologist. He was head of the University of Wisconsin geology department for 30 years. In 1942, he was awarded the Penrose Medal by the Geological Society of America, the highest award given in the geosciences. Biography Leith was born in Trempealeau (village), Wisconsin. He was hired by Charles R. Van Hise as a stenographer in 1892 to work on his publications, and was so taken by the work that he completed a bachelor's degree in geology at the University of Wisconsin in 1897 and a Ph.D. in 1901. In 1903, when Van Hise became president of the University of Wisconsin, he hired Leith as head of the geology department at the age of 28. Leith served as chair until 1934 (31 years), and remained with the department until he retired in 1945.

Charles R
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Cloquet River
The Cloquet River is a , accessed May 7, 2012 river in Minnesota, United States. It is the main tributary of the Saint Louis River. Name Cloquet ( ) River is known in the Ojibwe language as the ''Gaa-biitootigweyaag-ziibi'' ("River that parallels the Saint Louis River"). On the map of Stephen H. Long's expedition in 1823, it shows that stream as "Rapid River", and it is unnamed on the map by David Thompson in 1826 for the proposed routes of the international boundary. However, on the 1843 Joseph N. Nicollet map, the river is identified by its present name.Upham, Warren"Cloquet"in " Carlton County" section of ''Minnesota Place Names: A Geographical Encyclopedia''. Accessed July 27, 2013. Geography The Cloquet River generally flows in a southwesterly direction through Indian Lake, Alden Lake, and Island Lake, before emptying into the Saint Louis River. One can separate the river into two primary stretches, the upper stretch beginning at Cloquet Lake in Lake County as a small ...

Stream Piracy
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 instead down 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 additional water flowing down the capturing stream may accelerate erosion and encourage the development of a canyon (gorge). The now-dry valley of the original stream is known as a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Upham
The proglacial lakes of Minnesota were lakes created in what is now the U.S. state of Minnesota in central North America in the waning years of the last glacial period. As the Laurentide Ice Sheet decayed at the end of the Wisconsin glaciation, lakes were created in depressions or behind moraines left by the glaciers. Evidence for these lakes is provided by low relief topography and glaciolacustrine sedimentary deposits. Not all contemporaneous, these glacial lakes drained after the retreat of the lobes of the ice sheets that blocked their outlets, or whose meltwaters fed them. There were a number of large lakes, one of which, Glacial Lake Agassiz, was the largest body of freshwater known to have existed on the North American continent; there were also dozens of smaller and more transitory lakes filled from glacial meltwater, which shrank or dried as the ice sheet retreated north. Glacial Lake Agassiz Glacial Lake Agassiz was an enormous lake, larger in area than all the Grea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
