The Bobtail lode was discovered the following month. Gregory, brought thousands of prospectors and miners into the area, combing the hills for more gold veins. In May 1859 the discovery of gold in Gregory Gulch by its namesake, John H. History īlack Hawk was established in 1859. The ban was overturned by the Colorado Supreme Court in 2013. 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.
