2014 Map of Chapman Coulee

About this map

Milk River valley bottomlands define the southern edge of this landscape in Valley County, where the river winds through a broad floodplain before the terrain rises into a series of deeply etched drainages. This high-plains geography is characterized by its numerous named coulees, such as Alkali Coulee, Wire Grass Coulee, and Richardson Coulee, which serve as natural drainage paths toward the larger river system. The presence of the Cornwell Reservoir in the northern reaches and several creek systems, including Spring Cr and Cherry Cr, highlights the vital importance of water management in this arid stretch of Montana. Transportation through the area is anchored by Us-2, which cuts diagonally across the township grids, while local access is maintained through named tracks like Cornwell Rd and Jensen Trl, following the section lines of the Public Land Survey System.
