White River (Missouri River tributary)

The name stems from the water's white-gray color, a function of eroded sand, clay, and volcanic ash carried by the river[5] from its source near the Badlands.

[8] The White River rises in northwestern Nebraska, in the Pine Ridge escarpment north of Harrison, at an elevation of 4,861 feet (1,482 m) above sea level.

[2] It flows southeast then northeast past Fort Robinson and north of Crawford.

It crosses into southwestern South Dakota and flows north across the Pine Ridge Indian Reservation, then northeast, receiving Wounded Knee Creek and flowing between units of Badlands National Park.

It receives the Little White River about 15 miles (24 km) south of Murdo, and flows east to join the Missouri in Lake Francis Case about 15 miles (24 km) southwest of Chamberlain.
