2014 Map of Johnson Coulee West

About this map

McDonald Butte rises above a highly dissected landscape of drainage systems in McCone County, where the topography is defined by numerous winding coulees. The north-flowing Nelson Cr serves as the primary drainage through this area, joined by several named tributaries that have carved deep into the high plains. Features like Morris Coulee and Dogtown Coulee illustrate the intricate erosion patterns typical of this portion of eastern Montana. In the southern reach of the quadrangle, Coal Cr marks a transition in the watershed. The map details the Public Land Survey System grid across townships T19N and T20N, showing the sparse road network and stock ponds that support the region's ranching operations. The naming of Johnson Coulee, Garfield Coulee, and Crookers Coulee suggests the significance of these natural landmarks to early settlers and land managers in navigating this complex terrain.
