1971 Map of Carpp Ridge

USGS Topo · Published 1986

About this map

The Continental Divide snake through this high-altitude landscape on the boundary of Granite and Deer Lodge counties, marking the crest of the Beaverhead Mountain range. This 1971 survey captures the transition from managed timberlands within the Deerlodge National Forest to the protected reaches of the Anaconda Pintlar Wilderness. The terrain is defined by glacial basins and alpine water sources, including Carpp Lake, Sauer Lake, and the uniquely named Blue Grotto Spring. Evidence of early resource extraction persists at the Carpp Mine and an unnamed Mine in Dexter Basin, while recreational access is illustrated through a network of remote paths like the Hi Line Trail and Porter Ridge Trail. The northern edge of the map features the East Fork Res, highlighting the intersection of natural drainage and water management near Mid Fk Rock Cr.
