About this map

Boundary Lake sits directly on the international border on this high plains landscape in northern Glacier County. The terrain is defined by the significant drainage of Big Rock Coulee and its eastern branch, the East Fork Big Rock Coulee, which cut through the open country. This modern survey reflects the vast, sparsely populated nature of the Montana borderlands, where the primary infrastructure consists of rural routes like Reagan Rd and Altenberg Rd. The map illustrates the structured division of land through the Public Land Survey System, showing the grid sections of townships t37n r7w and t37n r6w as they meet the Canadian border.
