About this map

Kootenai National Forest dominates this landscape in Northwest Montana, where the terrain is defined by a chain of glacial waters. The hydrologic network is centered on Upper Thompson Lake, Middle Thompson Lake, and Lower Thompson Lake, which are linked by the Thompson River as it flows south toward the boundary of Sanders Co. These basins are fed by numerous mountain streams including Tallulah Cr, Slimmer Creek, and Davis Cr.

Human activity is concentrated along the lake shores and forest service corridors like Upper Thompson Lake Rd and ACM Rd N. The presence of the Campbell Ranch Airport in the southeastern corner near McGregor Cr provides an essential aviation link for this remote forest region. High points like Bowers Peak overlook the diverse aquatic features, including Rainbow Lake, Elk Lake, and Lost Lake, illustrating the complex drainage patterns at the intersection of Lincoln Co, Flathead Co, and Sanders Co.
