Casa Diablo (other)
Casa Diablo Hot Springs is a hot springs and active geothermal location, near Mammoth Lakes and the Eastern Sierra Nevada, in Mono County, eastern California. Geography It is within the northern part of the Long Valley Caldera volcanic feature and zone, and beside U.S. Highway 395. California State Route 203 branches off to the west from the Highway 395 interchange at Casa Diablo Hot Springs, leading to the Mammoth Lakes and ski resort area, and Devils Postpile National Monument. History Casa Diablo Hot Springs was once the site of a regularly erupting geyser. It is noted as a Native American mining and manufacturing site specializing in obsidian materials. Use of materials from this site is noted at least as early as the Millingstone Horizon. 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 . It was a relay station for the route to the mining ...

Mono County, California
Mono County ( ) is a county located in the east central portion of the U.S. state of California. As of the 2020 census, the population was 13,195, making it the fourth-least populous county in California. The county seat is Bridgeport. The county is located east of the Sierra Nevada between Yosemite National Park and Nevada. The only incorporated town in the county is Mammoth Lakes, which is located at the foot of Mammoth Mountain. 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. History Mono County was formed in 1861 from parts of Calaveras, Fresno and Mariposa counties. A portion of norther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bodie, California
Bodie ( ) is a ghost town in the Bodie Hills east of the Sierra Nevada mountain range in Mono County, California, United States. It is about southeast of Lake Tahoe, and east-southeast of Bridgeport, at an elevation of 8,379 feet (2554 m). Bodie became a boom town in after the discovery of a profitable line of gold; by 1879 it had a population of 7,000–10,000. The town went into decline in the subsequent decades and came to be described as a ghost town by .

Projectile Point
In North American archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives, spears, axes, hammers, and maces. Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites. They provide useful clues to the human past, including prehistoric trade. A distinctive form of point, identified though lithic analysis of the way it was made, is often a key diagnostic factor in identifying an archaeological industry or culture. Scientific techniques exist to track the specific kinds of rock or minerals that were used to make stone tools in various regions back to their original sources. As well as stone, projectile points were also made of worked wood, bone, antler, horn, or ivory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obsidian Hydration
Obsidian hydration dating (OHD) is a geochemical method of determining age in either absolute or relative terms of an artifact made of obsidian. Obsidian is a volcanic glass that was used by prehistoric people as a raw material in the manufacture of stone tools such as projectile points, knives, or other cutting tools through knapping, or breaking off pieces in a controlled manner, such as pressure flaking. Obsidian obeys the property of mineral hydration and absorbs water, when exposed to air at a well-defined rate. When an unworked nodule of obsidian is initially fractured, there is typically less than 1% water present. Over time, water slowly diffuses into the artifact forming a narrow "band," "rim," or "rind" that can be seen and measured with many different techniques such as a high-power microscope with 40–80 power magnification, depth profiling with SIMS (secondary ion mass spectrometry), and IR-PAS (infra red photoacoustic spectroscopy). In order to use obsidian hydration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hot Creek (Mono County, California)
Hot Creek, starting as Mammoth Creek, is a stream in Mono County of eastern California, in the Western United States. It is within the Inyo National Forest. Course Mammoth Creek The creek begins its course in the eastern Sierra Nevada named as Mammoth Creek. It originates as an outflow of Twin Lakes, just south of Mammoth Mountain and above the town of Mammoth Lakes. The stream is primarily sourced from melted snow water at above sea level. It is quite cold, rarely being above . Hot Creek As Mammoth Creek leaves the Sierra and flows east into the Long Valley Caldera it is joined by warmer water from geothermal springs at the Hot Creek State Fish Hatchery. From this confluence the stream is named Hot Creek, though its water temperature seldom exceeds until it reaches Hot Creek Gorge, east of Mammoth Lakes. In the Hot Creek Gorge, numerous hot springs near and in the stream bed add hot water into the stream. Its mouth is at the confluence with the Owens River upstream from ...

Mammoth Geothermal Complex
The Mammoth Geothermal Complex is a complex of 3 geothermal power stations located at Casa Diablo Hot Springs about east of Mammoth Lakes, California. The complex is owned by Ormat and operated by its subsidiary Mammoth Pacific. Description The complex consists of three binary cycle geothermal power stations, each with a nameplate capacity of 10 MW. Mammoth Pacific 1 (MP1) was commissioned in 1984 and was the first air-cooled geothermal power station in the world. Mammoth Pacific 2 (MPII) and PLES-1 were both commissioned in 1990 and use the same air-cooled technology. In 2005, the geothermal well field was expanded into "Basalt Canyon" just west of the three power stations. Two production wells were drilled and connected to the existing power plants. In 2014, Ormat replaced the 30-year old equipment of MP1 in order to improve its efficiency. Casa Diablo IV In 2006, Ormat proposed the construction of a 30 MW binary cycle geothermal power plant called "Casa Diablo IV" that wou ...

Pine City, California
Mammoth Lakes is a town in Mono County, California, and is the county's only incorporated community. It is located immediately to the east of Mammoth Mountain, at an elevation of . As of the 2020 United States Census, the population was 7,191, reflecting a 12.7% decrease from the 2010 Census. History The Mono people were the first settlers of the Mammoth Lakes area, thousands of years ago. They settled in the valley but traveled by foot to other areas when trading with different tribes. The European history of Mammoth Lakes started in 1877, when four prospectors staked a claim on Mineral Hill, south of the current town, along Old Mammoth Road. In 1878, the Mammoth Mining Company was organized to mine Mineral Hill, which caused a gold rush. By the end of 1878, 1500 people settled in the mining camp called Mammoth City. By 1880, the company had shut down, and by 1888, the population declined to less than 10 people. By the early 1900s, the town of Mammoth was informally establishe ...

Mineral Peak
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct p ...
