2014 Map of Hall Coulee

About this map

The international boundary between Canada and the United States defines the northern edge of this landscape in Glacier County. The high plains terrain is marked by significant topographical depressions and plateaus, most notably Hall Coulee and the adjacent Pikuni Flat and Freezeout Flat. Water management and natural drainage are central to the area's character, highlighted by the engineered Saint Mary Canal which cuts across the prairie to redirect vital water resources. The hydrology is further defined by the N Fork Milk River and various seasonal streams including Willow Cr and Hagerty Cr. Local infrastructure is sparse, consisting largely of unpaved transit routes like Galbreath Rd and Boarding School Rd, alongside historic paths such as the Squaw Flat Trl and McGovern Trl, reflecting the area's transition from traditional tribal lands to modern agricultural and conservation uses.
