Whetstone Indian Agency (South Dakota)
The Whetstone Agency succeeded the Upper Platte Agency in 1869, when it was moved from its Platte River location to the mouth of Whetstone Creek on the Missouri in Dakota Territory. Whetstone Agency was primarily responsible for the band of Brulé Sioux under Spotted Tail, but it was also responsible for other bands of Brulé, Oglala, and Miniconjou Sioux who lived near the agency. It was moved in 1871 and again in 1875, first to Big White Clay Creek and then to a site on the White River near the border between Dakota Territory and Nebraska. The name was changed in 1874 to the Spotted Tail Agency.
