|The Dew Drop Mine is one of a group of consolidated mines collectively known as the Big Five Mine. The area of Lefthand Creek in the Ward district, Boulder County, Colorado was one of the region's richest gold and silver producers by 1870. The Big Five Mining Group consolidated five mining properties around Lefthand Creek and California Gulch in 1897. The ores from these mines were transported to Camp Frances mills for processing by way of an adit tunnel. Contamination from the mine and mill areas was found to threaten drinking water supplies in the late 1990s. The area around the Big Five Mine tunnel, mill, and Captain Jack Mine was designated as a Superfund hazardous waste site in 2003.
