New Idria, California

The area is inside Area code 831. It is included in the Monterey Bay Unified Air Pollution Control District and the Panoche Elementary School District. San Benito Mountain, elevation , is located southeast. The nearest city is King City along U.S. Route 101. The New Idria Mercury Mine was named in honor of the world's then second largest quicksilver mine in what was then Idria, Austria, now Idrija, Slovenia; (Slovene pronunciation [ĭdrija], California English pronunciation [īdria].) The town grew to support the mining operations, but the mine closed in the 1970s. The town is currently an abandoned ghost town with more than 100 standing buildings, though vandalism has contributed to their deterioration in recent years. According to the US Geological Survey, both Idria (primary) and New Idria (variant) are recognized for federal use in describing the community. ==History==

The community was established to support the mine, which mainly extracted mercury, since cinnabar was abundant in the local rock formations. Mercury mining at the location began in 1854. At one time, the New Idria mines were America's second most productive mines, with the New Almaden mines in the vicinity of San Jose, about northwest, being the first. In 1894, the New Idria Post Office dropped the word "New" and the town become known as Idria. The New Idria Quicksilver Mining Company closed in 1972. In an 1871 report to the United States House of Representatives, the surveyor general of California, Sherman Day, noted "...that the country about the mine is a series of rough and precipitous mountains and hills, intersected by deep canons; that the greater portion of it is barren and unsuited for agricultural purposes; it is essentially a minieral region..." On May 30, 1974, the town and surrounding 2,000 acres were auctioned by Wershow Auctioneers, in So. San Francisco. The town has since become a ghost town. The United States Postal Service operated a post office, going by the name Idria, with the ZIP Code 95027. The post office closed on January 2, 1974. New Idria is a California Historical Landmark (#324) On July 30, 2010, a fire destroyed 13 buildings on the north side of town. ;Superfund Site In 2011, New Idria was re-listed as a U.S. Environmental Protection Agency (EPA) Superfund site, owing to unchecked mercury run-off and contamination. As of June, 2012, the entire section of the former town site on the south side of New Idria/Clear Creek road is fenced-off. == Environmental concerns in the area ==

The New Idria Mercury Mine was initially investigated in the 1990s by the EPA, for possible inclusion on the EPA's National Priorities List, but the site did not rank high enough at that time to be listed. A site reassessment was begun in 2002, and an expanded site assessment begun in 2009, which was concluded in October 2010. In March 2011, the EPA proposed New Idria to its National Priority List. Elevated levels of mercury were found downstream of the town, as well as significant levels of mercury and other heavy metals found within tailings piles on the site. The region has a long history of mining, with asbestos and chromium being mined in addition to mercury; the EPA's 2004 Risk Assessment for the nearby Clear Creek Management Area identified 86 separate abandoned mines in the vicinity. The natural rock formations in the area have been shedding asbestos-rich debris into stream valleys for millions of years The average New Idria rock contains 5-15% by volume short fiber asbestos. The 2010 edition of Rand McNally's The Road Atlas labels the area immediately south of New Idria as an "Asbestos Hazard Area". ==Mineral collecting==

The New Idria Mining District is known for its abundance of rare minerals such as benitoite, named after the San Benito River. Gem quality benitoite is only found in this area of the world. New Idria is also home to serpentinite rock. Many thousands of tectonic events acting on the serpentinite have produced extensive deposits of short-fiber asbestos. ==Climate==
