2014 Map of Mount Hefty OE N

About this map

The Flathead River flows southward through this borderland region where British Columbia meets Montana, defining a landscape shaped by glacial drainage and intricate creek systems. Positioned along the international boundary with Canada, the area is characterized by high-elevation water bodies like Beryl Lake and Marl Lake in the northeastern reaches. These alpine lakes feed into Beryl Cr, which joins the larger network of Howell Creek. The map documents a rugged watershed where numerous tributaries, including Cabin Cr, Burnham Cr, and Couldrey Cr, carve through the terrain toward the river valley. To the south, the boundary of the Flathead National Forest marks the transition into protected American lands. This 2014 survey captures the precise hydrography of the Upper Flathead, illustrating the remote drainage patterns of Calder Creek before they cross the border.
