Challis National Forest dominates this section of Custer County, where high mountain peaks and a complex drainage system define the geography. The landscape is marked by prominent landmarks such as Rye Grass Pinnacle and Red Butte, which overlook the high-elevation terrain of Eddy Basin. Access to this back-country region is facilitated by routes like Morgan Creek Rd and Lick Creek Rd, which follow the natural valleys carved by Morgan Creek and its many tributaries.
