Rivers in South Dakota
The Missouri River is a 4,130 km long tributary of the Mississippi and flows through the states of Montana, North Dakota, South Dakota, Nebraska, Iowa, Kansas and Missouri. This makes the Missouri longer than the actual Mississippi and could be described as the longest river in the USA. The Missouri is created by the confluence of the Jefferson River and Madison River in southwestern Montana.
Big Sioux River
With a length of only 470 km, the Big Sioux River is a rather short tributary of the Missouri River. The Big Sioux River originates in the extreme northeast of South Dakota and generally flows south towards its mouth in the Missouri River near Sioux City. Since the river forms waterfalls at one point called Sioux Falls, the city of Sioux Falls also originated here. The river forms part of the border between the states of South Dakota and Iowa.
The Cheyenne River is approximately 475 km long and rises in the northeast of the state of Wyoming. On its way through South Dakota, the tributary of the Missouri flows south of the Black Hills to unite with the Missouri at its mouth in Lake Oahe.
The James River, also called the Jim or simply the Dakota River, is a tributary of the Missouri River with a length of approx. 1,143 km. The James River rises relatively centrally in the state of North Dakota and flows south through the two Dakotas before it flows into the Missouri River near the city of Yankton on the border with Nebraska.
The White River is a 930 km long tributary of the Missouri River and flows through South Dakota in a northeastern direction. The source of the White River is in northwestern Nebraska. With its influence in Lake Francis Case, the White River and the Missouri River merge in southeastern South Dakota.

The mountain range of the Black Hills is located in western South Dakota and northeastern Wyoming. The Black Hills cover an area approximately 160 km long and 96 km wide. The history of this mountain range is particularly interesting. If these mountains were considered sacred to the Lakota-Sioux, settlers in the past searched and found gold, coal, iron and now even petroleum and uranium. The Black Hills are particularly interesting from a tourist perspective, as they include the Mount Rushmore National Memorial, the Crazy Horse Memorial, Custer State Park and two cave systems of outstanding importance, the Wind Cave National Park, the Jewel Cave National Monument and the Monolith Devils Tower National Monument.
