Badlands are formed by erosional processes, mainly that of water downcutting the soft clay.
It was established by political whim, not by a cartographer or geographer.
South Dakota.----Many have a rough shape of a rectangle, but Wyoming and Colorado seem to be nearest to a true rectangle.
South Dakota helped shape America in various ways: Gold was discovered in the Black Hills of South Dakota, shaping the way US treaties with the Native American tribes in the area were changed. Mount Rushmore National Memorial was created in the Black Hills of South Dakota, shaping the the tourist industry in South Dakota and the US. Carving of the monument also helped develop techniques used in future carvings and in mining. Land in South Dakota was opened to homesteaders, bringing many immigrants to the US. Dams on the Missouri River in South Dakota have provided recreation, electrical power, and water sources for many people.
North Dakota is roughly the shape of a rectangle. The capital of North Dakota is Bismarck and the largest city in the state is Fargo.
There were many factors that went in to determining the shape of South Dakota. The original Dakota Territory, formed in 1861, was formed by the area that was leftover when Minnesota became a state. The 1861 Dakota Territory also included most of present-day Montana and Wyoming. As new territories were formed, land was split off and added to the Dakota Territory so that, in 1868, the final Dakota Territory was formed. In 1889, the Dakota Territory was again split and formed two states, North Dakota and South Dakota. In an attempt to make the states a similar size, the states of North Dakota, South Dakota, Nebraska, and Kansas were all created by the US Congress to have approximately 3 degrees of latitude (about 207 miles in height). The Enabling Act of February 22, 1889 stated that the Dakota Territory "be divided on the line of the seventh standard parallel produced due west to the western boundary of said Territory" (45°50′N). Landforms were also a factor in forming South Dakota's border. The Missouri River forms a portion of the southeast corner of South Dakota. Lake Traverse, the Bois de Sioux River, and Big Stone Lake form a portion of South Dakota's eastern border with Minnesota.
