The Continental Divide winds through the center of this high-elevation landscape, marking the boundary between Deerlodge National Forest and Helena National Forest. The small settlement of Leadville sits just west of the divide, reflecting the region's mining heritage alongside Schurchs Tunnel to the south. The terrain is defined by a series of prominent peaks, including Sugarloaf Mtn in the northeast and Saratoga Mtn near the southern edge. The watershed is intricately carved by numerous drainages such as Rocker Gulch and the headwaters of the Boulder River. This 2020 survey reveals the complex network of forest roads like Rock Creek Rd and the prominent Continental Divide National Scenic Trail, which traces the ridgelines through some of Montana's most significant wilderness areas.
