About this map

Lava Beds National Monument dominates the northern reaches of this Siskiyou County landscape, where volcanic activity has shaped every landmark. The sheet highlights the immense Medicine Lake Glass Flow and the towering heights of Glass Mountain and Little Glass Mountain. These obsidian and pumice deposits are central to the area's geography, even supporting industrial activity at the Pumice Mine. Central to the map is Medicine Lake itself, surrounded by various water sources like Crystal Sprs and Schonchin Spring.

Transportation through this high-altitude terrain is marked by the presence of the Lumber RR, reflecting the region's timber history across the Modoc National Forest, Klamath National Forest, and Shasta National Forest. Significant cinder cones and buttes, including Schonchin Butte, Cinder Butte, and Mammoth Crater, provide clear evidence of the complex geological history that defines this intersection of three national forests.
