1984 Map of Centennial Mountain

USGS Topo · Published 1984

About this map

Rocky Boys Indian Reservation encompasses a significant portion of this landscape along the border of Chouteau and Hill Counties. The area is defined by its complex drainage network, where Big Sandy Creek and Frenchman Creek gather water from the surrounding slopes. Higher elevations are marked by the prominent Centennial Mountain and Little Bear Peak, which overlook the dense Assneyewin Timber. The map provides a detailed record of indigenous and local nomenclature through numerous watercourses such as Okeyquuaakkeo, Oosahquapahmoo, and Mistiguenou Creek. This 1984 provisional survey documents the land before modern development, showing the transition from mountain ridges to the Salt Coulee and Goin Creek bottomlands. The intricate contours reveal the varied terrain of the Bearpaw Mountains region, which served as a critical habitat and resource area for the communities within the reservation.
