Lava Beds National Monument dominates the northern half of this landscape, showcasing a complex volcanic topography of craters, caves, and natural bridges. The prominent Schonchin Butte stands as a focal point near the massive Schonchin Flow, surrounded by numerous named geological formations such as The Castles and Hippo Butte. The southern portion of the sheet transitions into the timbered lands of Modoc National Forest and Klamath National Forest. This 2015 survey reveals the intricate network of natural conduits like Symbol Bridge, Merrill Natural Bridge, and Ovis Bridge. Notable landmarks such as Heppe Chimney and Tickner Chimneys underscore the subterranean and surface volcanic activity that characterizes this portion of Siskiyou County, while Cinder Butte Rd provides access through the rugged terrain.
