All three cultures were stable until the United States Army moved them to Indian reservations in 1882 as part of the removal efforts that ended the Indian Wars. The Havasupai and Hualapai are descended from the Cerbat and still live in the immediate area. The village of Supai in the western part of the current park has been occupied for centuries. Adjacent to the eastern part of the park is the Navajo Nation, the largest reservation in the United States.
