About this map

Frenchman Creek carves a winding path through this corner of North-Central Montana, defining a landscape marked by complex drainage patterns and seasonal water catchments. The terrain is characterized by a series of deep coulees, including Coulter Coulee, Red Mud Coulee, and School Section Coulee, which channel runoff across the high plains. Human presence is evidenced by isolated water management features such as Morgan Reservoir and Coral Reservoir, essential for ranching and land use in this arid environment.

Running along the border of Phillips and Valley Counties, the map shows a network of remote access routes like Frenchman Rd and Genevieve Rd. Distinctive local names like Big Toe Flat and Bohner Coulee provide a glimpse into the regional vernacular. The eastern portion is dominated by the branches of Little Snake Cr and Jack Cr, illustrating the vital role of these small waterways in a region defined by its wide-open spaces.
