About this map

Marshall Peak stands as a prominent high point at the intersection of the Boise National Forest and Sawtooth National Forest, marking a complex drainage divide where Elmore, Blaine, and Camas counties meet. The landscape is defined by the headwaters of several critical Idaho waterways, notably the S Fork Boise River and the meandering Ross Fork which winds through the Ross Fork Basin.

Evidence of historical alpine activity is reflected in the naming of several deep canyons such as Eureka Gulch, Jakes Gulch, and Mill Gulch. To the south, Perkins Lake provides a rare concentrated water feature amidst a network of high-elevation streams like Emma Cr and Alturas Lake Cr. This 2013 survey illustrates the wilderness character of the region, emphasizing the natural boundaries formed by the ridges and creek beds that separate these three central Idaho counties.
