About this map

Schonchin Butte and the surrounding volcanic landscape dominate this northern California survey, illustrating a complex network of geological formations and primitive roads. The area is defined by massive lava features such as the Schonchin Flow and Callahan Flow, alongside dozens of prominent peaks including Whitney Butte, Bat Butte, and Eagle Nest Butte. These natural landmarks provided early explorers and settlers with clear navigational points across the high desert terrain.

Evidence of the region's subterranean activity is visible in the naming of numerous natural spans and volcanic vents, such as Merrill Natural Bridge, Symbol Bridge, and Heppe Chimney. Historic travel corridors like Lyons Rd and Tennant Lava Beds Rd thread between these formations, connecting isolated spots like Indian Well Campground and Hidden Valley to the broader Siskiyou County landscape. This 2012 record preserves the placement of unique features like Tickner Chimneys and The Castles, which remain critical for geologists and local historians studying the Modoc Plateau.
