About this map

Emigrant Gap defines this high-plains landscape along the international border in northern Glacier County. The land is shaped by the sophisticated water management of the Saint Mary Canal, which skirts the northern reaches of the quadrangle near the Canada-United States border. This hydraulic infrastructure represents a critical lifeline for the region's ranching economy, visible in the network of rural routes like Fox Ranch Rd and 3 C Bar Rd that cross the open terrain.

Waterways like the N Fork Milk River and Hagerty Cr cut through distinct topographic features such as Hungry Horse Flat and Pikuni Flat. To the south, the elevation rises toward Twin Buttes and the depression known as The Basin. This 2017 survey documents a modern snapshot of a vast grazing territory where traditional trails like the Mcgovern Trl and Squaw Flat Trl continue to mark the paths of movement through the coulees and flats.
