Blue Mountain is in eastern Calaveras County about 10 miles southeast of West Point. A number of narrow quartz veins exist in granodiorite, schist, and hornfels. The ore bodies are small and irregular but contain extremely abundant sulfides. The quartz often has a dark color. The principal properties have been the Black Wonder, Gold King, and Heckendorn mines.
