2020 Map of Three Sisters

About this map

The Continental Divide National Scenic Trail winds through the high-elevation divide that separates the Flathead National Forest and Lewis & Clark National Forest. This 2020 survey of the Lewis and Clark Range documents the complex watershed of the Spotted Bear River, which is fed by numerous drainages including Three Sisters Cr, Christopher Cr, and Hoop Cr. The topography is defined by prominent summits such as Lookout Mtn, Hahn Peak, and the namesake Three Sisters. The map illustrates the boundary between Flathead Co and Lewis and Clark Co as it follows the crest of the range, highlighting small alpine features like Lake Quiet, Suck Lake, and Hart Lake that punctuate the headwaters of the N Fork Lick Cr and S Fork Red Shale Cr.
