The Spencer Opal Mines are located in South Eastern Idaho, 65 miles north of Idaho Falls on I-15, 70 miles west of Yellowstone National Park, and 80 miles south of Dillon Montana. The mine was discovered in 1948 by two deer hunters and filed as a mining claim in 1952. The Stetler family acquired the property in 1964 and opened it to the "rockhounds" for digging in 1968. It is still owned and operated by the Stetler family.
