2020 Map of Twin Sisters

About this map

Twin Sisters stands as a prominent landmark at the intersection of the Payette National Forest and the Boise National Forest in this high-altitude region of Gem County. The landscape is defined by a dense network of drainages and ridges, where the Little Weiser River flows in the north and Squaw Creek cuts through the southern terrain. Key passage points like Mill Creek Summit and the winding Squaw Creek Rd indicate the historical importance of these mountain routes for forest access and resource management.
