About this map

The Swan Range defines the high-altitude topography of this portion of the Flathead National Forest, where steep drainages and jagged summits dominate the landscape. Named peaks such as Thunderbolt Mtn, Gildart Peak, and Warrior Mtn create a natural barrier along the border of Lake and Flathead counties. A network of high-country water bodies, including the Gildart Lakes, feeds into numerous creeks like Bunker Cr and Middle Fork Cr, illustrating the complex hydrology of this mountainous interior.

Accessibility is limited to primitive routes such as the Soup Creek Trl and various Forest Service developments, including Natl Forest Develop Road 2820 Rd. Strategic overlooks and crossings are marked by features like Inspiration Pass, Inspiration Point, and Napa Point. This survey captures a wild, high-elevation environment where land management boundaries intersect with the natural flow of the S Fork Lost Cr and Inspiration Cr.
