2020 Map of Beaupre Coulee

About this map

The international boundary between Canada and the United States of America defines the northern edge of this Toole County landscape. The high plains terrain is deeply incised by a series of dramatic drainages, including Beaupre Coulee, O'Laughlin Coulee, and Timber Coulee. These landforms dictate the placement of local infrastructure, where rural routes like Aschim Rd and Pederson Rd navigate the contours of the open range. Near the center of the quadrangle, Perkins Lake sits as a rare water feature in an otherwise arid environment characterized by the seasonal flow of Kicking Horse Cr. The presence of Coal Mine Rd and Sweet Grass Hills Rd suggests the historical importance of resource extraction and local transport networks connecting these remote northern sections of Montana. This modern survey reflects the enduring grid of the Public Land Survey System, which continues to shape the ranching and agricultural patterns of the region.
