The high volcanic plateau of Siskiyou County is defined here by the meeting of three major timber and grazing lands: Modoc National Forest, Klamath National Forest, and Shasta National Forest. At its center lies Medicine Lake, surrounded by unique geological formations like the Medicine Lake Glass Flow and the towering Little Glass Mountain. The map illustrates a landscape shaped by both ancient eruptions and early 20th-century utility, with features like Mammoth Crater and Schonchin Butte punctuating the terrain. Human presence is marked by isolated water sources such as Lairds Well and Doak Well, alongside the remote Lava Camp. Early industry is evidenced by the Pumice Mine near Pumice Stone Mtn, connected by a network of specialized routes including Lumber Road and Fire Camp Road.
