Mississippi River: North America’s Mighty River
Shortly after entering western North Dakotait begins to trend southeastward before continuing southward just south of Bismarck into northern and central South Dakota to Pierrewhere it again begins to trend southeastward.
Continuing through central and southern South Dakota, the river then forms a section of the South Dakota— Nebraska boundary, the Nebraska— Iowa boundary, the Nebraska— Missouri boundary, and the northern section of the Kansas —Missouri boundary.
At Kansas CityKansas, the river again turns to the east and, after flowing through Kansas CityMissouri, meanders eastward across west-central Missouri before heading southeastward again to Jefferson City.
There it makes its final eastward turn, flowing until it joins the Mississippi River about 10 miles 16 km north of St. The range of elevations within its basin is considerable: The flow of the Missouri and of most of its tributaries is exceedingly varied—the minimum flow being 4, cubic feet cubic metres per second and the maximumcubic feet 25, cubic metres per second.
With unprotected slopes and violent fluctuations in flow, erosion and silting are major problems. Chief tributaries include the CheyenneKansas, Niobrara, Osage, Platte, and Yellowstone rivers, flowing in on the south and west sides, and the James and Milk rivers, entering from the north.
For millennia, the area around the upper Missouri River was home to Native American peoples such as the BlackfeetHidatsaand Crow. The mouth of the river was first encountered by Europeans in —by the French explorers Jacques Marquette and Louis Jolliet while they were canoeing down the Mississippi River. In the early s French fur traders began to navigate upstream.
The first exploration of the river from its mouth to its headwaters was made in —05 during the Lewis and Clark Expedition. For many years commerce on the river was restricted to the fur trade, and the river was little used by the earliest American settlers moving west. The river's average discharge at Bismarck, 1, Sapphires are found in some spots along the river in western Montana.
When the glaciers retreated, the Missouri flowed in a new course along the south side of the Bearpaws, and the lower part of the Milk River tributary took over the original main channel. However, damming and channeling the river has kept it from reaching its natural sediment sources along most of its course.
The Missouri Meets the Mississippi
Reservoirs along the Missouri trap roughly Plains Indians Archaeological evidence, especially in Missouri, suggests that human beings first inhabited the watershed of the Missouri River between 10, and 12, years ago at the end of the Pleistocene. Over centuries, the Missouri River formed one of these main migration paths.
Most migratory groups that passed through the area eventually settled in the Ohio Valley and the lower Mississippi River Valley, but many, including the Mound buildersstayed along the Missouri, becoming the ancestors of the later Indigenous peoples of the Great Plains. Many migratory animals naturally inhabit the plains area. Before they were slaughtered by colonists, these animals, such as the buffaloprovided meat, clothing, and other everyday items; there were also great riparian areas in the river's floodplain that provided habitat for herbs and other staple foods.
Most of the Indigenous peoples in the region at that time had semi-nomadic cultures, with many tribes maintaining different summer and winter camps.
