1968 Map of Emigrant Gap

About this map

Emigrant Gap sits at the international boundary in the late 1960s, marking a rugged point of passage where the high plains of Glacier County meet the Alberta border. This landscape is defined by the complex water management systems of the Saint Mary Canal, which winds across the northern terrain to feed the North Fork Milk River. The map captures a largely unpopulated expanse of grazing land and coulees, including the wide plateau of Hungry Horse Flat and the depressions of The Basin. The border itself is meticulously delineated, showing the Blackfeet Indian Res Bdy and the transition into the Lethbridge District. Scattered infrastructure like the Gaging Sta and a Gravel Pit near Dubay Coulee point to the limited but vital human activity in this remote ranching and irrigation corridor.
