Alpha Hydraulic Diggings

The Alpha Hydraulic Diggings are located one mile north of what was the town of Alpha during the California Gold Rush in 1850, but the site is now near the unincorporated town of Washington, California. The diggings became a registered California Historical Landmark on January 29, 1958.
