Rapid City Indian School and Sioux Sanatorium (.pdf)

One of 28 off-reservation boarding schools built and operated by the Bureau of Indian Affairs, the school existed from 1898-1933 to serve Indian children of the Northern plains—including Sioux, Northern Cheyenne, Shoshone, Arapaho, Crow, and Flathead. The buildings were later used to house the Sioux Sanatorium, an institution established to treat Indians with tuberculosis.
