Lava Beds National Monument and the adjacent Modoc National Forest dominate this Siskiyou County landscape, defined by a series of volcanic formations and cinder cones. The map traces the rugged volcanic geology from Schonchin Butte and Modoc Crater in the north to Mammoth Crater and Indian Butte further south. A network of geologic and human history is visible through labels for a Geothermal Well and various Cinder Pits that suggest local industry and resource extraction.
