2017 Map of Pumice Desert West

About this map

The Crater Lake National Park boundary defines much of this southern Oregon landscape, where the volcanic geology of the High Cascades is on clear display. This 2017 survey shows a high-elevation wilderness dominated by prominent cinder cones and ridges, including Bald Crater, Red Cone, and Gaywas Peak. The vast, flat expanse of the Pumice Desert in the southeast stands in stark contrast to the surrounding timberlands of the Rogue River National Forest and Umpqua National Forest. Hydrological features include the headwaters of the Rogue River and its tributaries like Minnehaha Cr and National Cr, which originate from high-altitude sources such as Boundary Springs and Oasis Spring. This map is particularly valuable for hikers and researchers tracing the route of the Pacific Crest National Scenic Trail as it traverses the eastern volcanic ridges.
