Cheyenne and Arapaho Tribes
A nation today
Background
Two names sit beside Cheyenne and Arapaho on the Tribes' own front page: Tsistsistas and Hinono'ei. Their language and culture programs state their job as protecting and instructing for the preservation of tribal traditional customs, arts and language. Their government runs executive, legislative and judicial branches alongside a tribal council branch and a set of boards, commissions and task forces, and the Tribes run housing, education, elder services and health programs. Tribal offices are at 100 Red Moon Circle in Concho, Oklahoma. The Tribe's Department of Justice is charged under Article VII, Section 4(a) of their constitution with satisfying the executive branch's duty. Rocky Mountain National Park lists the Tribes among the nations whose homelands include what is now the park, and records that Hinono'ei and Tsistsistas bands were seasonal residents of the Rocky Mountains by the time settlers arrived.
