Wind River Indian Reservation The Eastern Shoshone and Northern Arapaho tribes share the Wind River Indian Reservation in central western Wyoming, near Lander. The reservation is home to 2,500 Eastern Shoshone and 5,000 Northern Arapaho. Chief Washakie established the reservation in 1868 as the result of negotiations with the federal government in the Fort Bridger Treaty, but the federal government forced the Northern Arapaho onto the Shoshone reservation in 1876 after it failed to provide a promised separate reservation. Today the Wind River Indian Reservation is jointly owned, with each tribe having a 50% interest in the land, water, and other natural resources. It is a sovereign, self-governed land with two independent governing bodies: the Eastern Shoshone Tribe and the Northern Arapaho Tribe. Until 2014, the Shoshone Business Council and Northern Arapaho Business Council met jointly as the Joint Business Council to decide matters that affect both tribes. Six elected council members from each tribe served on the joint council. Public lands The federal government owns nearly half of Wyoming's land (about ); the state owns another . Most of it is administered by the Bureau of Land Management and U.S. Forest Service in numerous national forests and a national grassland, not to mention vast swaths of "public" land and an air force base near Cheyenne.
