About this map

Bullwhacker Coulee and its many offshoots carve through this section of Blaine County, defining a landscape shaped by intermittent water and local ranching infrastructure. Small-scale water management is evident throughout the terrain, marked by several named catchments including Blanch Reservoir, Brush-Shack Reservoir, Bud Reservoir, and the central Sandpiper Reservoir. These features suggest the vital importance of water storage for livestock in this high plains environment.

Transportation through the coulees relies on established paths such as the Cow Island Trl, which traverses the northern half of the region. Other routes like Bullwhacker Rd and Three Mile Rd connect the various drainages, including Coal Mine Coulee and Christenson Br. The map also details the N Fork Lion Coulee in the southwest, illustrating the complex network of dry washes and seasonal streams that dominate this northern Montana territory.
