Ralston Creek is a tributary of Clear Creek, approximately 32 miles (51 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 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 first documented discovery of gold in the Rocky Mountain region occurred in June 1850, when Lewis Ralston, a Georgia prospector headed for the California gold fields, dipped his sluice pan into this stream near its mouth at Clear Creek. Ralston found about 1/4 ounce (6 g) of gold worth about five dollars. Ralston's companions named the stream Ralston's Creek in his honor, but they all left the next morning, drawn by the lure of the California gold fields.
In the spring of 1858, William Green Russell and his brothers searched the creek for gold. Later in the year, Lewis Ralston brought another group of prospectors back to the site of his first discovery.
