The name stems from the water's white-gray color, a function of eroded sand, clay, and volcanic ash carried by the river.〔Benke and Cushing, p. 445〕 Draining a basin of about ,〔 about of which is in South Dakota, the stream flows through a region of sparsely populated hills, plateaus, and badlands.〔Benke and Cushing, p. 449〕 The White River rises in northwestern Nebraska, in the Pine Ridge escarpment north of Harrison, at an elevation of above sea level.〔 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. At the northern edge of the reservation, it flows east-northeast and southeast, forming the northern boundary of the reservation and the southern boundary of Buffalo Gap National Grassland. It receives the Little White River about south of Murdo, and flows east to join the Missouri in Lake Francis Case about southwest of Chamberlain. The river sometimes has no flow, due to the dry climate surrounding its badlands and prairie basin, though thunderstorms can cause brief intense flow. The river near Chamberlain flows year-round. The White River has generally good-quality water.〔 ==See also== * *List of rivers of Nebraska *List of rivers of South Dakota 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「White River (Missouri River)」の詳細全文を読む スポンサード リンク
