About this map

Mt Thompson serves as a central landmark for this high-elevation region where the Deerlodge National Forest meets the Helena National Forest. The landscape is deeply carved by numerous drainages including Cataract Creek, Hoodoo Creek, and Clancy Creek. Evidence of historical mining activity is reflected in naming patterns across the quadrangle, with labels like Galena Gulch, Little Galena Gulch, and Boomerang Gulch suggesting the mineral-rich character of the Jefferson County terrain.

Industrial and residential development is concentrated in the southern portion near Fuller, where Cataract Creek flows toward the Boulder River. Local access is maintained through a network of specialized roads, such as High Ore Road and Silver Bell Road, which serve both the forested interior and small settlements like Comet. Large natural features such as the Occidental Plateau and Bluebird Flats provide a distinct contrast to the steep terrain of Curtain Gulch and McKenzie Gulch.
