The highest and greatest producing mines existed in Victor, with the Portland on Battle Mountain one of the great producers of gold. By 1899, Cripple Creek produced two-thirds of gold mined in Colorado, which was one fourth of full production in the United States. Over the years, many of the county's small towns and settlements have disappeared as open pit mining operations expand. In southern Teller County, mining expansion also eliminated Altman, once the highest town in elevation in the United States. Limited evidence remains of the recreation area, Pinnacle Park.
