Black Hawk is a home rule municipality located in Gilpin County, Colorado, United States. The city population was 127 at the 2020 United States Census, making Black Hawk the least populous city (rather than town) in Colorado. The tiny city is a historic mining settlement founded in 1859 during the Pike's Peak Gold Rush. Black Hawk is now a part of the Denver-Aurora-Lakewood, CO Metropolitan Statistical Area and the Front Range Urban Corridor.
Black Hawk is located adjacent to Central City, another historic mining settlement in Gregory Gulch. The two cities form the federally designated Central City/Black Hawk National Historic District. The area flourished during the mining boom of the late 19th century following the construction of mills and a railroad link to Golden. The town declined during the 20th century, but has been revived in recent years after the 1991 establishment of casino gambling following a statewide initiative in 1990. In early 2010, the Black Hawk city council passed a law banning the riding of bicycles in the town, drawing a reaction from bicycle advocacy groups and international press. The ban was overturned by the Colorado Supreme Court in 2013.
History
Black Hawk was established in 1859.
Mining boom
In May 1859 the discovery of gold in Gregory Gulch by its namesake, John H. Gregory, brought thousands of prospectors and miners into the area, combing the hills for more gold veins. The Bobtail lode was discovered the following month. Hardrock mining boomed for a few years, but then declined in the mid-1860s as the miners exhausted the shallow parts of the veins that contained free gold, and found that their amalgamation mills could not recover gold from the deeper sulfide ores.
Nathaniel P. Hill built Colorado's first successful ore smelter in Black Hawk in 1868. Hill's smelter could recover gold from the sulfide ores, an achievement that saved hardrock mining in Black Hawk, Central City, and Idaho Springs from ruin. Other smelters were built nearby. Black Hawk's advantageous location on North Clear Creek made it the center of ore processing for the area, and it became known as the "City of Mills".
The Colorado Central Railroad extended its line to the town in 1872. A restored depot and locomotive are on display on the east side of downtown. Black Hawk was also served by the two-foot-gauge Gilpin Tramway which climbed from Black Hawk to the mines above Central City. Many historic buildings in the town have been restored following the opening of the casinos in 1991.
Gambling boom
The town has been in heated competition for gambling revenue with its neighbor Central City since casinos opened in both towns in 1991. Development of the area down Clear Creek from the historic Black Hawk townsite lining State Highway 119 has flourished. Gamblers from Denver pass the Blackhawk casinos before they arrive at Central City, and, as a result, Black Hawk has realized much more revenue from gambling than Central City. Gambling in Black Hawk also benefits from less restrictive zoning codes; while Central City until recently limited building heights to to preserve the historic character of the town, Black Hawk has no such limits. In an attempt to close the competitive gap, Central City built the Central City Parkway from Interstate 70 near Idaho Springs as an alternative route, leading guests first to Central City, and then to Black Hawk. The Central City Parkway opened November 19, 2004. However, Black Hawk continues to have three times the number of casinos, and generates more than seven times the gambling revenue that Central City does.
Although the 1990 statewide referendum allowing casino gambling in Black Hawk was promoted as a way to promote historic preservation in Black Hawk, critics have charged that it has had the opposite effect, and that the historic appearance of Black Hawk has been sacrificed to allow construction of the large casinos.
Tax from the gambling revenue provides funding for the State Historical Fund, administered by the Colorado Office of Archaeology and Historic Preservation.
