Spotted Tail Indian Agency (South Dakota)

History
The Spotted Tail Agency was the successor to the Whetstone Agency. It received its name from the leader of the band of Brulé Sioux which it served. In 1878, the agency was moved to a location on Rosebud Creek near its confluence with the South Fork of the White River and the name was changed to the Rosebud Agency.
