The Sacagawea River winds through this section of Petroleum County, cutting across a landscape defined by deep drainages and cattle-country roads. This 2014 survey documents the remote network of trails and water sources essential to the region's ranching economy, including the Horse Camp Trl and Crooked Creek Rd. Topographic variations are marked by numerous coulees, such as Hanson Coulee and Spring Coulee, which channel seasonal runoff toward the river. In the southeastern reaches, the Drag Reservoir and its namesake Drag Cr illustrate the managed hydrology required to sustain life in this arid part of Montana. The map reflects a modern era of land management while preserving the traditional place names that have defined these range lands for generations.
