The Carson River is a northwestern Nevada river that empties into the Carson Sink, an endorheic basin. The main stem of the river is 131 miles (211 km) long although the addition of the East Fork makes the total length 205 miles (330 km), traversing five counties: Alpine County in California and Douglas, Storey, Lyon, and Churchill Counties in Nevada, as well as the Consolidated Municipality of Carson City, Nevada. The river is named for Kit Carson, who guided John C. Frémont's expedition westward up the Carson Valley and across Carson Pass in winter, 1844. The river made the National Priorities List (NPL) on October 30, 1990 as the Carson River Mercury Superfund site (CRMS) due to investigations that showed trace amounts of mercury in the wildlife and watershed sediments.
The Sulphur Bank Mine is located near Clearlake Oaks and Clear Lake in Lake County, California. The 150-acre (0.61 km2) mine became one of the most noted mercury producers in the world.
The Kennedy Gold Mine is a gold mine in Jackson, California, one of the deepest mines on the Mother Lode. It closed in 1942 and together with nearby Argonaut Mine, is registered as California Historical Landmark No. 786. It has since been re-opened as a tourist attraction.
Burke Canyon is the canyon of the Burke-Canyon Creek, which runs through the northernmost part of Shoshone County, Idaho, U.S., within the northeastern Silver Valley. A hotbed for mining in the late-nineteenth and twentieth centuries, Burke Canyon now contains several ghost towns and remnants of former communities along Idaho State Highway 4, which runs northeast through the narrow canyon to the Montana border.
Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US. Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc, quartz, and pyrite intermittently from the 1860s until 1963. The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper, and cadmium. One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.
The Treadwell gold mine was on the south side of Douglas Island, .5-mile (0.80 km) east of downtown Douglas and southeast of downtown Juneau, owned and operated by John Treadwell. Composed of four sub-sites, Treadwell was in its time the largest hard rock gold mine in the world, employing over 2,000 people. Between 1881 and 1922, over 3 million troy ounces of gold were extracted. Not much remains today except for a few crumbling buildings and a "glory hole". Although John Treadwell had twelve years of experience in both placer and lode mines, he was a carpenter and builder by trade who had come to Alaska prior to the Klondike Gold Rush.
The Midnite Mine is an inactive uranium mine in the Selkirk Mountains of the state of Washington that operated from 1955 to 1965 and again from 1968 to 1981. Located within the reservation of the Spokane Tribe of Indians, it is approximately 8 miles (13 km) from Wellpinit, Stevens County. The mine was listed as a Superfund site under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) on May 11, 2000. In addition to elevated levels of radioactivity, heavy metals mobilized in uranium acid mine drainage pose a potential threat to human health and the environment.
The Leadville mining district, located in the Colorado Mineral Belt, was the most productive silver-mining district in the state of Colorado and hosts one of the largest lead-zinc-silver deposits in the world. Oro City, an early Colorado gold placer mining town located about a mile east of Leadville in California Gulch, was the location to one of the richest placer gold strikes in Colorado, with estimated gold production of 120,000–150,000 ozt, worth $2.5 to $3 million at the then-price of $20.67 per troy ounce.
The Milltown Reservoir Sediments Superfund Site is a major Superfund site in Missoula County, Montana, seven miles east of Missoula. It was added to the National Priorities List in 1983 when arsenic groundwater contamination was found in the Milltown area. The contamination resulted from a massive flood three years after its construction in 1905, which washed millions of tons of mine waste into the Clark Fork River, ultimately ending up behind the Milltown Dam.
The Anaconda Copper Mine is an open pit copper mine in Lyon County, Nevada that was owned and operated by the Anaconda Mining Company. It is located adjacent to the town of Yerington. A company town, Weed Heights, was built to support the mining operation, which ran from 1952 until 1978. The Anaconda Copper Mine is one of three EPA Superfund sites in the state of Nevada.
Mining in the United States has been active since the beginning of colonial times, but became a major industry in the 19th century with a number of new mineral discoveries causing a series of mining rushes. In 2015, the value of coal, metals, and industrial minerals mined in the United States was US$109.6 billion. 158,000 workers were directly employed by the mining industry.
Uranium mining and the Navajo people began in 1944 in northeastern Arizona, northwestern New Mexico, and southeastern Utah.
Leviathan Mine is a United States superfund site at an abandoned open-pit sulfur mine located in Alpine County, California. The mine is located on the eastern slope of the Sierra Nevada at about 7,000-foot (2,100 m) elevation, 6 miles (9.7 km) east of Markleeville and 24 miles (39 km) southeast of Lake Tahoe. The mine site comprises approximately 250 acres (100 ha) 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.
The Saint Sava Serbian Orthodox Church is a Serbian Orthodox church in Jackson, California. Built in 1894, the church was the first Serbian Orthodox church in America. Amador County had a large Serbian-American population in the late 1800s due to the California Gold Rush, and the county's Serbs established the St. Sava Church Organization of Amador County in 1886–87; the organization was responsible for purchasing land for and building the church, and the effort was led by Sevastijan Dabović. The church's original design had an Eastern Orthodox influence, complete with an onion dome; while the dome was later replaced by a bell tower, the church's stained glass windows and use of icons still give it a distinctive Eastern Orthodox character. The church has been used for Serbian-American religious and social activities since its opening and is now part of the Serbian Orthodox Eparchy of Western America.
The Atlas Asbestos Mine Superfund Site is located within the Clear Creek Management Area near Fresno County, eighteen miles northwest of Coalinga, California. The mine started operating in 1963, covering 435 acres of a large naturally occurring asbestos deposit. The mine closed in 1979 and was placed in the EPA's National Priorities List (NPL) in 1983 due to the pollution of asbestos in the surrounding soil, air and water creating potential health hazards for local populations and environment.
The California Gulch site consists of approximately 18 square miles in Lake County, Colorado. The area includes the city of Leadville, parts of the Leadville Historic Mining District and a section of the Arkansas River from the confluence of California Gulch downstream to the confluence of Two-Bit Gulch. The site was listed as a Superfund site in 1983.
The Lava Cap Mine is an abandoned gold mine in Nevada County, California. The mine is located 5 miles (8.0 km) southeast of Nevada City. The site is undergoing cleanup by the United States Environmental Protection Agency for arsenic contamination.
