Uravan (a contraction of uranium/vanadium [2] ) is a former uranium mining town [3] in western Montrose County, Colorado, United States, which still appears on some maps. The town was a company town established by U. S. Vanadium Corporation in 1936 to extract the rich vanadium ore in the region. As a byproduct of vanadium extraction, small amounts of uranium were also produced, at the time mostly used as a yellow pigment for ceramics.
The town was located approximately 90 miles (140 km) south-southwest of Grand Junction along the San Miguel River. At one time, over 800 people lived in Uravan, and the town housed a school, a trading center (store), medical facilities, tennis courts, a recreation center, and a pool. The school and some other facilities remained operational until at least 1983, however Uravan was shut down by mid-1985, and no trace of its former buildings remain. Uravan is now an uninhabited, undeveloped Superfund site.
There are several prehistoric sites near Uravan on the Colorado State Register of Historic Properties: [4]
In 1885, placer gold was discovered in a tributary of the San Miguel River, Mesa Creek, nine miles from Nucla, Colorado. The Montrose Placer Mining Company constructed the Hanging Flume on the east wall of Dolores River Canyon. [5] : 54–56
During World War II, Uravan provided part of the uranium needed by the Manhattan Project for the first atomic bomb. Because of wartime secrecy the Manhattan Project would only publicly admit to purchasing the vanadium, and did not pay the uranium miners for the uranium ore (in a much later lawsuit, many miners were able to reclaim lost profits from the U.S. government).
In the beginning of the Cold War, to ensure adequate supplies of uranium for national defense, the United States Congress passed the U.S. Atomic Energy Act of 1946, creating the U.S. Atomic Energy Commission (AEC) which had the power to withdraw prospective uranium mining land from public purchase, and also to manipulate the price of uranium to meet national needs. By setting a high price for uranium ore, the AEC created a uranium "boom" in the early 1950s, which attracted many prospectors to the four corners region of the country. Uravan's fortunes grew as it became one of the major "yellowcake boomtowns" in the region.
American military requirements of uranium declined in the 1960s, and the government completed its uranium procurement program by the end of 1970. Simultaneously, a new market emerged: commercial nuclear power plants. However, the U.S. domestic uranium mining industry collapsed in the late 1970s and early 1980s, due to lack of new nuclear power plants, and to low-price uranium imported from Canada.
The town had been in decline for several years; the decision was made to close Uravan in 1985 and then commence a large-scale clean-up of the entire site. Environmental cleanup of the site commenced in 1986 and was essentially completed by 2001. (EPA, 2010, Five-Year Review) All the buildings have been removed and the site regraded and replanted. All that remains is a turnoff and interpretive sign along State Highway 141.
On May 6, 2012 the Montrose County Board of County Commissioners signed the Omnibus Agreement with Dow Chemical, giving them three tracts of land: Ballpark Parcel #1, a 133-acre plot between Hwy. 141 and the San Miguel River, Ballpark Parcel #2, approximately ten acres northwest of the first parcel, and the townsite property, located between County Roads EE22 and Y11. [6] Montrose County agreed to accept this property on behalf of the Rimrocker Historical Society of Western Montrose County, which has worked since 1990 to preserve and interpret the history of Uravan. The Rimrocker Historical Society and Montrose County entered into a long-term lease on May 1, 2013 for a 17-acre section of Ballpark parcel #1, with the intention of building a museum and campground on the property. The Rimrocker Historical Society of Western Montrose County hosts the annual Uranium History Celebration and Reunion Picnic at Historic Uravan, Colorado every August. For the 100th anniversary of the original Joe Jr. Mill in 2012, over 1,000 people attended.
San Miguel County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 8,072. The county seat is Telluride. The county is named for the San Miguel River.

Dolores County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 2,326. The county seat is Dove Creek.
Nucla is a statutory town in Montrose County, Colorado, United States. The population was 585 as of the 2020 census, down from 711 in 2010. Its name comes from the town founders' intent that it serve as a "nucleus" for the surrounding farms and mines, although it has since come to be associated with the growth of uranium mining in the region.
Carnotite is a potassium uranium vanadate radioactive mineral with chemical formula K2(UO2)2(VO4)2·3H2O. The water content can vary and small amounts of calcium, barium, magnesium, iron, and sodium are often present.
The Western Slope is the part of the state of Colorado west of the Continental Divide. Bodies of water west of the Divide flow toward the Pacific Ocean; water that falls and flows east of the Divide heads east toward the Gulf of Mexico. The Western Slope encompasses about 33% of the state, but has just 10% of the state's residents. The eastern part of the state, including the San Luis Valley and the Front Range, is the more populous portion of the state.
The San Miguel River is a tributary of the Dolores River, approximately 81 miles (130 km) long, in southwestern Colorado in the United States. It rises in the San Juan Mountains southeast of Telluride and flows northwest, along the southern slope of the Uncompahgre Plateau, past the towns of Placerville and Nucla and joins the Dolores in western Montrose County approximately 15 miles (24 km) east of the state line with Utah.
Weldon Spring Ordnance Works (WSOW) was a 17,323-acre (70.10 km2) U.S. Government-owned, contractor-operated (GOCO) facility in St. Charles County, Missouri, 55 km west of St. Louis. The site was originally operated by the Atlas Powder Company during World War II from 1941 to 1945 to produce explosives. The Atomic Energy Commission acquired part of the property in 1955, and Mallinckrodt, Inc. processed uranium ore from 1957 to 1966 under contract. The site has been divided into several parcels, and ownership has transferred over the years. Two portions of the original WSOW property are now Superfund sites that require substantial cleanup efforts. The environmental remediation of the WSOW site is currently designated as a major project of the Defense Environmental Restoration Program of the United States Department of Defense. Part of the original property is still used by the Army Reserve as the Weldon Spring Training Area.

Uranium mining in the United States produced 173,875 pounds (78.9 tonnes) of U3O8 in 2019, 88% lower than the 2018 production of 1,447,945 pounds (656.8 tonnes) of U3O8 and the lowest US annual production since 1948. The 2019 production represents 0.3% of the anticipated uranium fuel requirements of the US's nuclear power reactors for the year.
Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado. The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
Uranium mining in Utah, a state of the United States, has a history going back more than 100 years. Uranium mining started as a byproduct of vanadium mining about 1900, became a byproduct of radium mining about 1910, then back to a byproduct of vanadium when the radium price fell in the 1920s. Utah saw a uranium boom in the late 1940s and early 1950s, but uranium mining declined in the 1980s. Since 2001 there has been a revival of interest in uranium mining, as a result of higher uranium prices.
Uranium mining in New Mexico was a significant industry from the early 1950s until the early 1980s. Although New Mexico has the second largest identified uranium ore reserves of any state in the United States, no uranium ore has been mined in New Mexico since 1998.
The Paradox Trail is located in western Montrose County, Colorado and traverses a route of over 118 miles (190 km) through various terrain. The trail was rerouted 17 miles due to a trespass issue near the Tabeguache area north of Nucla in 2017. The trail links with two other long-distance trails in the region, the Tabeguache Trail to the east on the Uncompahgre Plateau and the Kokopelli Trail to the west in the La Sal Mountains of Utah. These three trails together form the "Grand Loop", a grueling 360 mile course.
Colorado mining history is a chronology of precious metal mining, fuel extraction, building material quarrying, and rare earth mining.
Paramontroseite (V4+O2) is a relatively rare orthorhombic vanadium oxide mineral in the Ramsdellite group. Synthetic paramontroseite may have applications in medicine, batteries and electronics.
A yellowcake boomtown also known as a uranium boomtown, is a town or community that rapidly increases in population and economics due to the discovery of uranium ore-bearing minerals, and the development of uranium mining, milling or enrichment activities. After these activities cease, the town "goes bust" and the population decreases rapidly.
