## History

The first documented discovery of gold in the Rocky Mountain region occurred on June 22, 1850, when Lewis Ralston, a Georgia prospector traveling with a party headed for the California gold fields, dipped his sluice pan into a small stream near its confluence with Clear Creek. He found about ¼ troy ounce (8 g) of gold, then worth about five dollars (about $550 USD today.) While Ralston was elated, the rest of the party was unimpressed and continued on to California the next morning. Ralston continued panning for gold, but after a few days gave up and caught up with his party. The site of Lewis Ralston's gold discovery now lies along Ralston Creek in the City of Arvada's Gold Strike Park.
In 1858, Ralston brought another group of prospectors back to the site of his first discovery. Ralston and most of the miners gave up after a few days, but several miners found gold upstream along the South Platte River. The placer gold in the area soon played out, but hard rock deposits of gold were found in the mountains to the west. Some of the miners abandoned their search for gold and returned to farm the rich bottom land along Ralston Creek and Clear Creek. They found an eager market for their crops among other gold seekers. The Territory of Colorado was formed on February 28, 1861, and the farms in the valley expanded to feed the growing population of the region.
In 1870, the Colorado Central Railroad laid tracks through the area on its route from Golden to link up with the Kansas Pacific Railroad and the Denver Pacific Railroad at Jersey Junction, 3 miles (5 km) north of Denver. On December 1, 1870, Benjamin F. Wadsworth and Louis A. Reno platted the Ralston Point townsite along the railroad. To avoid confusion with other communities along Ralston Creek, Ralston Point was soon renamed Arvada in honor of Hiram Arvada Haskin, brother-in-law of settler Mary Wadsworth. The Arvada, Colorado, post office opened on February 16, 1871, with Benjamin Wadsworth as the first postmaster. Colorado was granted statehood on August 1, 1876, and the Town of Arvada was incorporated on August 14, 1904. A vibrant agricultural community, Arvada was once known as the "Celery Capital of the World."
Arvada grew rapidly during the latter half of the 20th century as a suburb of nearby Denver, the state capital. Arvada became a Statutory City on October 31, 1951, and a Home Rule Municipality on July 23, 1963. By the end of the millennium, the population of Arvada exceeded 100,000.
