2017 Map of Lost Creek

About this map

Fort Peck Lake and the Missouri River define the northern and western margins of this Garfield County landscape, where the high plains meet the vast reservoir system. The topography is deeply incised by a network of drainage features such as Ghost Coulee, Deadman Coulee, and Brandon Coulee, which draw toward the river valley. This 2017 survey reveals a sparsely populated ranching region, anchored by landforms like Brandon Butte and the winding course of Lost Creek. Transportation is limited to remote corridors like Lost Creek Rd and Brusett Rd, illustrating the isolation of the Missouri Breaks region. The map also delineates the boundary between Phillips and Garfield counties, marking where these administrative lines cross the expansive waters of the lake.
