Blue Earth River
The Blue Earth River ( dak, Makhátho Wakpá) is a tributary of the Minnesota River, long, in southern Minnesota in the United States. Two of its headwaters tributaries, the Middle Branch Blue Earth River and the West Branch Blue Earth River, also flow for short distances in northern Iowa. By volume, it is the Minnesota River's largest tributary, accounting for 46% of the Minnesota's flow at the rivers' confluence in Mankato. Via the Minnesota River, the Blue Earth River is part of the watershed of the Mississippi River, draining an area of in an agricultural region. Ninety percent of the river's watershed is in Minnesota. It is a Minnesota Department of Natural Resources designated Water Trail. History The river was named for former deposits of bluish-green clay, no longer visible, along the banks of the river. The stream was called ''Makato Osa Watapa'' by the Dakota Indians, meaning "the river where blue earth is gathered." The French explorer Pierre-Charles Le Sueur esta ...

Blue Earth County, Minnesota
Blue Earth County is a county in the State of Minnesota. As of the 2020 census, the population was 69,112. Its county seat is Mankato. The county is named for the Blue Earth River and for the deposits of blue-green clay once evident along the banks of the Blue Earth River. Blue Earth County is part of the Mankato-North Mankato metropolitan area. History The area of Blue Earth County was once occupied by the Dakota Indians. French explorer Pierre-Charles Le Sueur was an early explorer in this area, arriving where the Minnesota and Blue Earth rivers meet. He made an unsuccessful attempt to mine copper from the blue earth. The area remained under French control until 1803 when it passed to the United States in the Louisiana Purchase. When Minnesota became a territory in 1849, the territorial government became interested in settling the river valley. In 1850 the first steamboat trip, starting in St. Paul, traveled on the Minnesota River and came to the Blue Earth River. The fir ...

Fur Trade
The fur trade is a worldwide industry dealing in the acquisition and sale of animal fur. Since the establishment of a world fur market in the early modern period, furs of boreal, polar and cold temperate mammalian animals have been the most valued. Historically the trade stimulated the exploration and colonization of Siberia, northern North America, and the South Shetland and South Sandwich Islands. Today the importance of the fur trade has diminished; it is based on pelts produced at fur farms and regulated fur-bearer trapping, but has become controversial. Animal rights organizations oppose the fur trade, citing that animals are brutally killed and sometimes skinned alive. Fur has been replaced in some clothing by synthetic imitations, for example, as in ruffs on hoods of parkas. Continental fur trade Russian fur trade Before the European colonization of the Americas, Russia was a major supplier of fur pelts to Western Europe and parts of Asia. Its trade developed in ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Fort L'Huillier
Fort L'Huillier (sometimes spelled Le Hillier) was a short-lived fortification in New France located near the confluence of the Blue Earth and Le Sueur Rivers in what is now Minnesota. The garrison, which originally held about 30 men, was built beginning in the autumn of 1700 under the direction of Pierre-Charles Le Sueur, a French trader and explorer interested in mining a blue clay that he thought was copper ore. It was named in honor of a metallurgical assayer, Rémy-François L'Huillier. Le Sueur left the fort in 1701 to take samples to New Orleans for further analysis. While he was gone, however, the fort was apparently attacked and abandoned by 1702, and no more was heard of the remaining men. In addition, the blue clay was found to be worthless, not the copper ore Le Sueur had hoped. The fort was southwest of the present city of Mankato Mankato ( ) is a city in Blue Earth, Nicollet, and Le Sueur counties in the state of Minnesota. The population was 44,488 accord ...

Pierre-Charles Le Sueur
Pierre-Charles Le Sueur (c. 1657, Artois, France – 17 July 1704, Havana, Cuba) was a French fur trader and explorer in North America, recognized as the first known European to explore the Minnesota River valley. Le Sueur came to Canada with the Jesuits to their mission at Sault Sainte Marie, but very soon he turned himself to fur trade and became a coureur des bois. He was fluent in several Native languages, which was crucial to his success in trade. Around 1683, he received some samples of bluish clay from the middle reaches of a tributary of the Mississippi and took it back to France to be analyzed. A chemist, Alexandre L'Huillier, deemed it to be copper ore. Le Sueur returned to New France to mine this ore, but was waylayed by, among other things, a prison term for overreaching his trade privileges. He was present at the formal assertion of French sovereignty of Canada, declared in 1689 by Nicholas Perrot at Green Bay. Eventually, however, he was given a royal commiss ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Trail
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where 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 a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...
