2017 Map of Pumice Desert East

About this map

Crater Lake National Park occupies the southern half of this landscape, where the volcanic geology of the High Cascades is evident in the prominent rise of Timber Crater. The terrain is defined by the intersection of three major protected areas, as the park boundary meets the Umpqua National Forest to the northwest and the Winema National Forest to the northeast. A significant stretch of the Pacific Crest National Scenic Trail winds through the western portion of the map, following the high ground near Summit Rock and the edge of the Pumice Desert. This open, arid expanse contrasts with the surrounding timberlands, illustrating the unique drainage patterns of the region where seasonal watercourses like Desert Cr and Tiny Cr navigate the porous volcanic soils. To the south, high points like Grouse Hill and Sharp Peak mark the transition toward the caldera rim beyond the map's southern edge.
