RALSTON CREEK (COLORADO)

'Ralston Creek' is a tributary of Clear Creek, approximately 15 miles (24 km) long, in central Colorado in the United States. It drains a suburban and urban area of the northwestern Denver Metropolitan Area. It rises in the foothills in northeastern Gilpin County, in southern Golden Gate Canyon State Park. It descends through a valley eastward into Jefferson, following Drew Hill Road (County Road 57), emerging from the mountains approximately 3 miles (5 km) north of Golden, where it is impounded to form Ralston Reservoir and Arvada/Blunn Reservoir on both sides of Colorado State Highway 93. It flows eastward through Arvada and joins Clear Creek from the north in southeast Arvada, near the intersection of Sheridan Avenue and Interstate 76.
The creek is noted as the site of early prospecting for gold during of the Spring of 1858 by William Green Russell and his brothers. ''See'' Colorado Gold Rush.
