Lewis and Clark Pass stands as a focal point in this high-elevation landscape, where the Continental Divide separates the headwaters of the Missouri and Columbia River systems. Located along the boundary of the Lewis & Clark National Forest and Helena National Forest, the terrain is defined by prominent peaks including Blowout Mtn, Red Mtn, and Sugarloaf Mtn. The hydrology of the region is equally complex, featuring the deep drainages of Alice Creek and the Alice Creek Basin in the south, while the northern slopes feed into Falls Creek and the Cuniff Basin. This survey illustrates the intricate network of gulches and ridges, such as Wildcat Gulch and Falls Creek Ridge, that historically dictated travel through the Lewis and Clark Range.
