Casa Diablo is a location in the Sierra Nevada in Mono County, eastern California, United States. Casa Diablo Hot Springs was named “House of the Devil”, by early explorers, for its boiling hot springs, rising steam and geysers.
This locale is noted as a Native American mining and manufacturing site specializing in obsidian materials. [1] Use of materials from this site is noted at least as early as the Millingstone Horizon. [2] Peoples as distant as the coastal Chumash people traded for material from this Obsidian source.
Casa Diablo became a stage stop along the Bishop Creek to Bodie stagecoach route in 1878 . It was a relay station for the route to the mining camps of Mammoth City, Mill City, Mineral Peak and Pine City. In 1881, Casa Diablo stage station ceased operating and was later used for other business as a trading post, a seasonal resort, a tavern, a gas station, a grocery store, a hardware store and a lumber yard. In 1983, it was transformed into a geothermal electric generating plant. [3]

Other locations, such as June Lake, are also famous as skiing and fishing resorts. Located in the middle of the county is Mono Lake, a vital habitat for millions of migratory and nesting birds. The lake is located in a wild natural setting, with pinnacles of tufa arising out of the salty and alkaline lake. Also located in Mono County is Bodie, the official state gold rush ghost town, which is now a California State Historic Park.

The Mono–Inyo Craters are a volcanic chain of craters, domes and lava flows in Mono County, Eastern California. The chain stretches 25 miles (40 km) from the northwest shore of Mono Lake to the south of Mammoth Mountain. The Mono Lake Volcanic Field forms the northernmost part of the chain and consists of two volcanic islands in the lake and one cinder cone volcano on its northwest shore. Most of the Mono Craters, which make up the bulk of the northern part of the Mono–Inyo chain, are phreatic volcanoes that have since been either plugged or over-topped by rhyolite domes and lava flows. The Inyo volcanic chain form much of the southern part of the chain and consist of phreatic explosion pits, and rhyolitic lava flows and domes. The southernmost part of the chain consists of fumaroles and explosion pits on Mammoth Mountain and a set of cinder cones south of the mountain; the latter are called the Red Cones.

Convict Lake is a lake located in Mono County, California, United States, situated in the Sherwin Range of the Sierra Nevada. It is known for its turquoise-blue water, the dramatic mountains that surround it, the trout fishing it affords, and its unusual history. The lake was renamed from its traditional Mono name by American settlers after an incident on September 23, 1871, in which a group of convicts escaped from prison in Carson City, Nevada, and took refuge near the lake. They were pursued by a posse, and after it caught up to the convicts, a shootout followed, in which a number of both posse members and convicts were killed or wounded. The remaining convicts who survived initially escaped but were eventually captured to be taken back to prison. They were lynched instead.
