Question: Berlin–Ichthyosaur State Park is located in a ghost town that was established in which year ?

full_context: Document 1: Ghost Town, Oakland, California: Ghost Town (sometimes spelled Ghosttown) is the informal name of the Foster Hoover Historic District neighborhood in West Oakland, Oakland, California. The community is known for its violence and blight . Some people believe the name originates from a drug king pin who referred to the area as a ghost town due to the shortage of other drug dealers whose absence was attributed to the king pin's dominance over the area. Others believe it derives from the two former casket companies located side by side on Filbert Street between 30th and 32nd Streets, while others claim that the presence of ghostly white people in an historically black neighborhood gave it its name. Ghost Town stretches from 27th Street to 35th Street in the area immediately southwest of the MacArthur Maze. Others see the neighborhood bounded by Adeline on the West and San Pablo on the East. Ghost Town Farms, one of the more successful expressions of urban agriculture activity in Oakland is located in the heart of the district at 2727 Martin Luther King Jr. Way, between 27th and 28th Streets. The area is also one of Oakland's many open-air art galleries, with exceptional muralist work continually on exhibition, particularly along Martin Luther King Jr. Way. This neighborhood has an active citizen crime patrol, including one group of seniors who walk the neighborhood weekly to get physical exercise and report blight. Jerry Brown, governor of California and former Mayor of Oakland stated: "Instead of an omnibus crime bill, you have to deal with shootings in Ghost Town in West Oakland and sideshows in East Oakland." Brown made attempts to turn around the blighted West Oakland neighborhood after "60 Minutes" featured it in a television profile. Housing prices have increased. So has drug dealing, especially since nearby parks were closed by the City of Oakland. Prostitution, in 2015, has been on the decline for at least a decade.
Document 2: Berlin–Ichthyosaur State Park: Berlin–Ichthyosaur State Park is a public recreation area and historic preserve that protects undisturbed ichthyosaur fossils and the ghost town of Berlin in far northwestern Nye County, Nevada.

The town began publishing its own newspaper in 1907. The location of the town was ideal as it was on the stagecoach route to Rhyolite and Beatty. It was also near the Amargosa River, allowing sufficient water for drinking and for two mills and an ice house. Gold Center also sold water to Rhyolite and Carrara. The Tonopah and Tidewater Railroad, the Las Vegas & Tonopah Railroad and the Bullfrog Goldfield Railroad all ran through Gold Center. Gold Center also had the first brewery in the area which was built underground to maintain a cool temperature.
Document 4: Silver City, Utah: Silver City is a ghost town located at the mouth of Dragon Canyon on the west flank of the East Tintic Mountains in northeast Juab County in central Utah, United States. It was a silver mining town approximately 90 mi south-southwest of Salt Lake City, Utah. This area was considered part of the Tintic Mining District and also produced bismuth, copper, gold, and lead. Settlement began with the first mining strikes here in 1869. Silver City was inhabited until 1930 after the mines ran out. Jesse Knight, known as the "Mormon Wizard" for his ability to find ore easily, decided to build a smelter in Silver City because it had the flattest ground in all of the Tintic Mining District. Silver City had several mines in 1890, but the mines hit water and were abandoned. Now there is nothing left other than a few holes where mines were, and a number of tailings piles.

Document 12: Jericho Mountain State Park: Jericho Mountain State Park (also referred to as Jericho Lake State Park) is located in the White Mountains in Berlin, New Hampshire, United States. The park was created in 2005 with the acquisition by the New Hampshire Division of Forests and Lands of two abutting properties: a 230 acre city park centered on Jericho Lake, and a 7200 acre piece of private property to the south. The city park was established in the 1970s with the construction of Jericho Lake, a flood control reservoir built to regulate the flow of the Dead River through the city center of Berlin, located downstream. The city added a small recreational park adjacent to the lake which included a beach, bath houses, picnic sites with grills, and a shelter that is still used for functions to this day. The large private parcel was acquired by the state park system to provide a location for the first network of all-terrain vehicle (ATV) trails on state land in New Hampshire.

Document 15: Leviathan Mine: Leviathan Mine is a United States superfund site (CERCLIS ID: CAD98067685) at an abandoned open-pit sulfur mine located in Alpine County, California. The mine is located at on the eastern slope of the Sierra Nevada at about 7,000 ft elevation, 6 mi east of Markleeville and 24 mi southeast of Lake Tahoe. The mine site comprises approximately 250 acre of land surrounded by the Toiyabe National Forest, which is only accessible a few months a year. The approximately 22 million tons of sulfur ore-containing crushed rock at the mine are responsible for contaminating the Leviathan and Aspen Creek, which join with Mountaineer Creek to form Bryant Creek which ultimately empties into the East Fork of the Carson River. These water bodies are listed as 303(d) impaired. The site location is seismically active.
