The Nome mining district, also known as the Cape Nome mining district, is a gold mining district in the U.S. state of Alaska.
 It was discovered in 1898 when Erik Lindblom, Jafet Lindeberg and John Brynteson, the "Three Lucky Swedes", found placer gold deposits on Anvil Creek and on the Snake River, a few miles from the future site of Nome.
 Word of the strike caused a major gold rush to Nome in the spring of 1899.
The Fairbanks mining district is a gold-mining area in the U.S. state of Alaska.
 Placer mining began near Fairbanks in July 1902, after Felix Pedro (real name Felice Pedroni), an Italian immigrant and Tom Gilmore discovered gold in the hills north of the Tanana and Chena Rivers in 1901.
 Pedro died exactly eight years after finding the richest gold placer he would ever know.
 By 1903 a new rush started, and prospectors staked thousands of claims.
 However, mining results were disappointing during the summer of 1903, with little gold recovered.
 Then Dennis O'Shea struck it rich on Fairbanks Creek, No. 8 Above.
 This was one of the richest claims in the Fairbanks Mining District and paid as high as $136 to the pan (gold @ $20/ounce).
 Discoveries on Cleary and Ester Creeks followed, and almost two-thirds of the gold mined in the Tanana hills before 1910 came from these three creeks.
 Total production of gold was more than $ 30 million.
 Towns grew on every creek with a combined population of 1,600 residents.
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.
Iron Mountain, in southwestern Utah, United States is the namesake of Iron County.
 Its summit is at 7815 ft It has a long history of iron mining, in the form of magnetite and hematite.
 Mining at this site goes back to Brigham Young and Mormon pioneers in the 1850s.
 The early history of this mining can be seen at Iron Mission State Park in nearby Cedar City, Utah.
 It is one of three major peaks in the Iron Mountain Mining District.
The Big River is a tributary of the Meramec River in east-central Missouri.
 The river rises in western Iron County ( ), near the summit of Johnson Mountain and the locale of Enough; it flows through Washington County, Saint Francois County, and Jefferson County.
 It forms part of the boundary between Jefferson County and Saint Francois County and also part of the boundary between Jefferson County and Washington County.
 It empties into the Meramec River opposite Eureka ( ), where the Meramec forms the border between Jefferson County and Saint Louis County.
 The river flows through Washington State Park, St. Francois State Park, and the Lead Belt mining district.
 The elevation of the river at its source is approximately 1300 ft above sea level and at its mouth about 400 ft .
 The length of the river is approximately 145 mi , while the airline distance between source and mouth is about 56 mi .
 Its watershed area is 955 sqmi .
Colorado Mining District was primarily a silver and gold mining district organized in El Dorado Canyon, New Mexico Territory on the west shore of the Colorado River in what is now Clark County, Nevada.
 The Colorado District was part of Arizona Territory from 1863 to 1869.
 In 1869, the land of Arizona Territory north and west of the Colorado River east to the 114th meridian of longitude, including the Colorado District, was turned over to Nevada.
Prospect Creek is a very small settlement approximately 180 mi north of present-day Fairbanks and 25 mi southeast of present-day Bettles, Alaska.
 Years ago it was home to numerous mining expeditions and the camp for the building of the Trans-Alaska Pipeline System (TAPS).
 Today, it is the location of Pump Station 5 (Jim River Station) of the TAPS.
 Prospect Creek is also home to the United States record for lowest temperature.
 On January 23, 1971 the record low temperature of -80 F was recorded.
 Wildlife can be found there even with its extreme changes in temperature; local fauna include anything from black and brown bears to bald eagles.
 The elevation of Prospect Creek is 643 ft above sea level.
 Nearby Moore Creek is widely known for its gold and quartz mining and sits alongside Prospect Creek in Alaska’s Innoko Mining District (Moorecreek Mining Line, MML).
 The Innoko Mining District is famous for its findings of large quartz.
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 state park covers more than 1100 acre at an elevation of 7000 ft on the western slope of central Nevada's Shoshone mountain range, 23 mi east of Gabbs.
The Berlin Historic District encompasses the ghost town of Berlin in Nye County, Nevada.
 The town was established in 1897 as part of the Union Mining District after the opening of the Berlin Mine the previous year.
 The town never prospered to the same extent as other boom towns like Tonopah and Goldfield, and declined following the Panic of 1907.
 The town was largely abandoned by 1911.
 The site was acquired by the state of Nevada as part of Berlin–Ichthyosaur State Park in 1970.
Victor is a statutory city in Teller County, Colorado, United States.
 Gold was discovered in Victor in the late 19th century, an omen of the future of the town.
 With Cripple Creek, the mining district became the second largest gold mining district in the country and realized approximately $10 billion of mined gold in 2010 dollars.
 It reached its peak around the turn of the century when there were about 18,000 residents in the town.
 Depleted ore in mines, labor strife and the exodus of miners during World War I caused a steep decline in the city's economy, from which it has never recovered.
 The population was 397 at the 2010 census.
 There is a resumed mining effort on Battle Mountain.

Question: What is the elevation of the state park that is in a town established in 1897 as part of the Union Mining District?
Answer: 7000 ft
