The Flathead River winds through this international border region, where the remote mountain terrain of Flathead National Forest meets the line between Montana and Canada. The landscape is defined by a network of drainage systems, including the westward-flowing Burnham Cr, Couldrey Cr, and Calder Cr, which carve through the high elevations. In the north, high-altitude water bodies like Beryl Lake and Marl Lake feed into Beryl Cr, eventually contributing to the larger Howell Creek system. This 2017 survey illustrates a wilderness nearly devoid of modern infrastructure, preserving the primitive character of the upper Flathead drainage as it crosses from Flathead County into British Columbia.
