In practice the Arapaho did not wish to locate permanently at an agency shared by the Sioux. They were belittled by leaders of the more powerful Sioux including Red Cloud, and wanted to avoid being culturally subsumed within the Lakota Nation. Instead, the Arapaho hoped for a reservation of their own. In 1868-69, the Arapaho briefly sought to locate with the linguistically-related Gros Ventres at the agency on the Milk River in Montana, but left after a smallpox epidemic. Further, Arapaho priest and leader Weasel Bear had a vision that the Arapaho would find a permanent home closer to the Rocky Mountains, and not on the Great Plains. The Arapaho way of life had historically included significant use of mountain hunting grounds, especially in the Colorado Rockies around Estes Park, but also including the Snowy Range, the Bighorns, the Black Hills, and the Laramie Range.
