2014 Map of Pumice Desert West

About this map

The volcanic landscape of the High Cascades is documented here at the intersection of Crater Lake National Park, Umpqua National Forest, and Rogue River National Forest. The geography is defined by prominent cinder cones and peaks including Bald Crater, Red Cone, and Oasis Butte, which rise above the unique geology of the Pumice Desert. Significant water sources emerge from the porous volcanic rock, most notably at Boundary Springs, the headwaters of the Rogue River, and Oasis Spring near National Cr. The map captures the infrastructure of the park and forest systems, including the Pacific Crest National Scenic Trail as it traverses the southern ridges near Grouse Hill and the established route of the W Diamond Lake Hwy cutting across the northern forest tracts. This 2014 survey illustrates the complex boundary management where Douglas and Klamath counties meet.
