2023 Map of Hall Coulee

About this map

The international boundary between Canada and the United States defines the northern edge of this high-plains landscape. The Saint Mary Canal serves as a critical piece of water infrastructure, cutting across the terrain north of the winding North Fork Milk River. This area is characterized by vast, open benches and drainage systems including Hall Coulee and Willow Creek. Transport through this borderland relies on a network of unpaved routes such as Whiskey Gap Rd and Weathered Rd, which navigate between the elevated Freezeout Flat and Pikuni Flat. The presence of several smaller watercourses like Freeze Out Creek and Hagerty Creek illustrates the complex drainage patterns required to manage seasonal runoff in this part of Glacier County.
