About this map

Boundary Lake sits directly on the international border on this high-plains Montana landscape, where the northern limit of Glacier County meets the Canadian frontier. The terrain is defined by the deep incisions of Big Rock Coulee and its East Fork Big Rock Coulee, which snake across the township sections of T37N and T36N. This modern survey illustrates the sparse, open character of the borderlands, where human presence is largely limited to the section-line grids and isolated routes like Reagan Rd and Altenberg Rd. The map provides a clear record of contemporary land divisions and topographical drainage patterns in a remote region where the high prairie begins to dip toward the northern water systems.
