About this map

Flathead National Forest land dominates this high-altitude landscape along the border of Lake and Flathead counties. The topography is defined by the soaring peaks of the Swan Range, including Thunderbolt Mtn, Warrior Mtn, and Tranquil Mtn. The map reveals a complex network of glacial cirques and high-mountain basins, many holding remote water bodies such as Bunker Lake, Scout Lake, and the Gildart Lakes.

Transport through this wilderness is limited to foot trails and forest development roads, highlighting the isolation of the region. Notable routes like Alpine 7 and the Soup Creek Trl navigate the sharp ridges, crossing through Inspiration Pass and providing access to vantage points like Napa Point and Inspiration Point. This survey details the source waters for several drainages, where Bunker Creek, S Lost Creek, and Gorge Creek carve deep valleys through the timbered slopes.
