2017 Map of Mount Thompson
USGS Topo · Published 2017About this map
The Boulder River flows through the southern portion of this region, where the settlements of Basin and Fuller are situated along the river's path and the Frontage Rd / Basin 15. This area is defined by its deep integration with the Deerlodge National Forest and Helena National Forest, illustrating a landscape shaped by both conservation and mountain resource extraction. Numerous gulches, such as Galena Gulch and Boomerang Gulch, descend from the heights of Mt Thompson and Sugarloaf Mtn, hinting at the mineral-driven history of Jefferson County. The presence of Comet and local routes like Silver Bell Rd and Cattle Drive Rd suggest a legacy of mining and ranching that persists in the geographic nomenclature of the Occidental Plateau.
