2020 Map of Whetstone Ridge

About this map

Bitterroot-Rock Creek Divide serves as a primary geographic spine across this high-elevation landscape, marking the boundary between Granite and Ravalli counties. This wilderness terrain is shared between Deerlodge National Forest and Bitterroot National Forest, where steep drainages such as Ross Fork and S Fork Rock Cr flow from the peaks of the Anaconda Range. The map documents a sparsely developed area defined by its hydrology and relief, from the namesake Whetstone Ridge to the high-altitude waters of Green Canyon Lake and Little Fish Lake. Notable local identifiers like Cow Camp Meadows and Frogpond Basin provide specific points of reference for those navigating the backcountry. Human infrastructure is minimal, limited to remote routes like Co RD 80 and Co RD 5110 winding through the foothills.
