1985 Map of Pumice Desert West

USGS Topo · Published 1985

About this map

The Crater Lake National Park boundary defines this landscape, where the northern volcanic reaches meet the Rogue River National Forest and Umpqua National Forest. This 1985 survey captures a high-elevation environment dominated by volcanic features like Bald Crater and Desert Cone. The map identifies critical water sources in an otherwise arid volcanic plateau, including Boundary Springs, which serves as the headwaters for the Rogue River, and the isolated Oasis Spring near Oasis Butte. The Pacific Crest National Scenic Trail winds along the southern edge of the sheet, crossing the Pumice Desert. This area, located near the Douglas Co Klamath Co line, illustrates the transition from the heavily forested slopes of Sherwood Butte to the open, cinder-covered plains that characterize the region north of the main caldera.
