2014 Map of Coulter Coulee

About this map

Phillips and Valley counties meet along a sharp North-South boundary in this high plains landscape of northern Montana. The terrain is defined by a series of dramatic drainages and plateaus, most notably Big Toe Flat and the expansive Coulter Coulee. Water management is central to the area's geography, evidenced by isolated ranching infrastructure such as Morgan Reservoir and Carol Reservoir. These features, along with the meandering paths of Snake Cr and Little Snake Cr, illustrate the seasonal water cycles essential to this region. The map captures a network of rural routes including Barnard Rd and Upper Frenchman Rd that navigate between named draws like Red Mud Coulee and Shed Coulee, providing a clear view of land use and topography in this corner of the Big Sky state.
