Some Geography

South-Dakota Topographic Regions Map
Topographic Map of South Dakota showing the location of the Black Hills, the Missouri Plateau, and the Coteau des Prairies. (click map to enlarge)
The state covers an area of 199,730 km² (77,116 sq mi), [1] in comparison, it is about twice as large as Iceland or South Korea. Compared with other US states, South Dakota is almost nine times larger than New Jersey, but it would fit into Texas three and a half times.

The Missouri is the longest river in North America; it flows north to south through the center of South Dakota. Near the state capital Pierre, the river turns southeast, and further downstream, it forms a section of the state border with Nebraska.

The principal western feeder rivers of the Missouri in South Dakota (from north to south) are the Grand River, the Moreau River, the Cheyenne River, the Bad River, and the White River.
The James River (aka Dakota River) is another tributary of the Missouri; it flows from north to south and drains the lowlands of the Dakotas. The Big Sioux River in eastern South Dakota rises in the Coteau des Prairies and generally flows southward; it forms the state's border with Iowa in the southeast and empties into the Missouri.

South Dakota's landscape in the east is dominated by the Coteau des Prairies, an upland (plateau) with numerous small glacial lakes. The plateau is 320 km long and 160 km wide (200 mi by 100 mi); it is separated by the James River Basin from the Coteau du Missouri, also known as the Missouri Plateau. The plateau represents a typical landscape of the Great Plains, with low, undulating rolling hills, potholes, grasslands, and incised stream valleys.

In the southwest are the geographical highlights of South Dakota, the Badlands, and the Black Hills. The Black Hills is a small, isolated mountain range with towering rocks and ponderosa pines rising from the Great Plains, for the Sioux and Cheyenne people the sacred center of the world.

Highest Point
The state's highest point is Black Elk Peak (formerly known as Harney Peak) at an elevation of 2,207 m (7,242 ft), situated in the Black Elk Wilderness area of the Black Hills.

Mount Rushmore National Memorial

Four miles to the east of Black Elk Peak is the Mount Rushmore National Memorial. It features some 18 m (60 ft) high sculptures of the heads of four United States presidents. The project of carving Rushmore was undertaken to increase tourism in the Black Hills region.

The United States seized the area of previously granted land from the Lakota tribe after the Great Sioux War of 1876. To the Plains Indians, the Black Hills area is sacred. The remote wilderness became of sudden interest for the White Men when gold was found in the 1870s. When the miners left some years later, the region’s economy sagged. To crank up tourism to the remote area, an idea was born, carve one of the oldest rock on Earth into a national monument.
Work began in 1927 under the direction of sculptor Gutzon Borglum and a ceremony overseen by then President Calvin Coolidge. In 1941 the monument was (more or less) completed. For the local Indians, it was a desecration of their sacred lands. [2][3][4]

The Badlands in southwestern South Dakota is an amazing collection of eroded buttes, pinnacles, spires, and the largest undisturbed mixed grass prairie in the United States. The White River Badlands are a significant paleontological resource; they contain the largest assemblage of known late Eocene (56 to 33.9 million years ago) and Oligocene (33.9 million to 23 million years ago) mammal fossils.
