2014 Map of Lake Marshall

About this map

Flathead National Forest and Lolo National Forest converge in this high-altitude drainage, where the headwaters of several major Montana river systems take shape. The terrain is defined by the sharp divide between the Swan River flowing north and the W Fork Clearwater River and its tributaries moving south and east. Prominent summits like Sunset Peak, West Fork Point, and Mt Henry anchor the ridgelines, overlooking numerous alpine water bodies including Lake Marshall, Lindbergh Lake, and Lake Dinah. The forest road network, featuring routes such as Colt Lake Rd and Upper Marshall Lake Rd, reflects the area's ongoing management and its use as a corridor for access through the rugged Swan Valley and Clearwater basins.
