The City of Arvada is a Home Rule Municipality located in Jefferson and Adams counties in the Denver metropolitan area of the U.S. State of Colorado. Olde Town Arvada is located 7 miles (11 km) northwest of the Colorado State Capitol in Denver. The 2010 United States Census recorded 106,433 residents, making Arvada the ninth most populous city in Colorado. The first documented discovery of gold in the Rocky Mountain region occurred on June 22, 1850, when Lewis Ralston, a Georgia prospector headed for the California gold fields, dipped his sluice pan into a small stream near its mouth at Clear Creek. Ralston found about 1/4 ounce (6 g) of gold then 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. During the Pike's Peak Gold Rush in 1858, Ralston brought another group of prospectors back to the site of his first discovery.
