About this map

The Pryor Mountains dominate this high-altitude terrain in south-central Montana, where the 2014 survey reveals a landscape of steep canyons and limestone features. This area within the Custer National Forest is defined by notable subterranean and surface geology, most famously the Big Ice Cave situated along Cave Ridge. The map details a complex network of seasonal drainages and springs essential for high-country life, including Trappers Cabin Spring and Roberts Spring.

The landscape is marked by significant topographical relief, from the heights of Big Pryor Mtn down into deep incisions like Bear Canyon and Cave Canyon. Cattlemen and early surveyors named many of these landforms, leaving behind labels like Roberts Bench, Harsten Flat, and Tibbs Hollow. The convergence of Big Horn Co and Carbon Co lines cuts through this wilderness, where the elevation changes support diverse environments ranging from Tony Island to the narrow corridors of Mill Hollow.
