Eastern Shoshone Tribe

Eastern Shoshone Tribe Information


The Eastern Shoshone Tribe lived in the Wind River mountain range and its environs for some 12,000 years. Today, they live on the Wind River Indian Reservation with the Northern Arapaho Tribe in central Wyoming. The Eastern Shoshone are known for their Plains horse culture. They acquired the horse in 1700 and it completely changed their lifestyles. They became proficient hunters thus they became fierce warriors. In 1868, Shoshone Chief Washakie signed the Fort Bridger Treaty that reserved 3.5 million acres in western Wyoming for the exclusive use of the Eastern Shoshone Tribe. Ten years later the federal government moved the landless Northern Arapaho Tribe onto the WRIR. Years passed and the U.S. Government chipped away at the reservation several times.

Today, the Shoshone Tribe has successfully reintroduced a thriving buffalo herd to their lands thanks to a cooperative effort between the National Wildlife Foundation, US Fish and Wildlife Service and a first-ever, tribal government-to-tribal government bison transfer with the Fort Peck Tribes. Reverend Roberts, the Episcopal Missionary who spent 66 years with the Shoshone and Arapaho people documented the last buffalo taken within the WRIR by members of either tribe occurred in 1885. Buffalo bones, skulls and even the relict wallows that buffalo created can still be found around areas of the WRIR. Buffalo remain spiritually and culturally important to the Eastern Shoshone as each part of the animal can be used in some way. Buffalo also increases biodiversity by benefitting many other organisms on the landscape such as, insects, butterflies, reptiles, and culturally important plants and mammals. Certain bird species benefit from buffalo that are listed as a species of concern by the US Fish and Wildlife Service, such as the ferruginous hawk, the mountain plover and the burrowing owl. The Shoshone Tribal Buffalo Representative Jason Baldes provides educational presentations to schools, students, community members and tourists that are interested.

The Eastern Shoshone Tribe is governed by a General Council which consists of adult tribal members and also the Shoshone Business Council-- comprised of six elected tribal members. There are currently about 4,400 tribal members. The WRIR is the seventh-largest Indian reservation in the United States by area, and the fifth-largest American Indian reservation by population.
