Mining boom

Black Hawk, 1864

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.^[11] 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.^[12]

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".^[13]

The Colorado Central Railroad extended its line to the town in 1872.^[11] 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 53 feet (16 m) 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.^[14]

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.^{[15][16][17][18]}

Tax from the gambling revenue provides funding for the State Historical Fund, administered by the Colorado Office of Archaeology and Historic Preservation.^[19]

Bicycling ban controversy

In February 2013, the Colorado Supreme Court overturned a citywide ban on bicycle traffic through Black Hawk, ruling that the city had failed to comply with state traffic law.^[9] In 2010, the Black Hawk banned bicycle use on most of the streets in the city. The ban was prompted by a surge in traffic following the change in maximum casino betting limits from $5 to $100. Black Hawk City Manager Michael Copp said that the city council, which passed the new law, believed it was best for the casinos and their patrons. The penalty for riding a bicycle through Black Hawk was a $68 fine.^[20][21] Bicycle advocacy groups challenged the bike ban, with the case ultimately going to the Colorado Supreme Court.^[22][23] State Highway 119 and County Road 279 in Black Hawk are part of the Great Parks Bicycle Route and the Peak to Peak Scenic Byway touring route.

Transportation

The Black Hawk & Central City Tramway, operated by the cities of Black Hawk and Central City, provides a free shuttle between the two towns. Ramblin Express and Ace Express Coaches provides transportation from Denver.^[28]
