USGS Topo · Published 2011About this map
Willow Mountain and Skalkaho Mountain anchor this high-altitude landscape in Ravalli County, where resource extraction and watershed management define the human footprint. The map documents several industrial sites, most notably the Vermiculite Mine in the southern reaches and two specifically located section-based operations, including the SW NW Section 16 Mine and the NE SE Section 26 Mine.
