2011 Map of Thoeny Hills West

USGS Topo · Published 2011

About this map

Thoeny Hills and the surrounding rangeland of Phillips County define this high-plains landscape along the Montana-Saskatchewan border. The map illustrates a region managed for water resources in a semi-arid environment, characterized by numerous small-scale water management features. Prominent among these are Clausen Dam, PR-83 Dam, and Burke Number 1 Dam, which collect runoff for local utility. The natural drainage of Cottonwood Creek and the deep incisions of Dunham Coulee and Kennedy Coulee carve through the terrain, while Grag Reservoir provides a significant focal point for the western portion of the quadrangle. This 2011 survey documents a sparsely settled agricultural and ranching district where the placement of dams and reservoirs remains critical to land use.
