2011 Map of Pumice Desert West

About this map

Crater Lake National Park defines the southern portion of this landscape, where the headwaters of the Rogue River emerge at Boundary Springs. The terrain reflects a complex volcanic history, characterized by features like the wide Pumice Desert and prominent summits such as Bald Crater and Desert Cone. This 2011 survey captures a high-elevation wilderness transition, tracing the path of the Pacific Crest National Scenic Trl as it winds through the southern ridges. North of the park boundary, the hydrology is defined by the westward flow of National Creek and Silent Creek, while human transit is limited to the corridors of the Old Diamond Lake Rd and various forest service routes. The map provides an essential record of this protected ecosystem, from the alpine seclusion of West Lake to the distinct geological formation of Twin Knobs.
