USGS Topo · Published 2021About this map
The volcanic landscape of Siskiyou County is defined here by the convergence of the Klamath National Forest, Shasta National Forest, and Modoc National Forest. This terrain is dominated by remarkable geological features like the massive obsidian-rich Little Glass Mtn and the striking Tilted Rock Lava Flow. To the south, a dense concentration of volcanic vents includes Giant Crater, Shastine Crater, and Chimney Crater, illustrating the intense geothermal activity that shaped this region.
