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.
