El Dorado County is the birthplace of the California Gold Rush — James Marshall's 1848 discovery at Coloma sparked westward migration and transformed the continent. The American River and its tributaries remain working placer streams where small-scale dredging and highbanking continue under suction dredge restrictions. Deep-channel paleochannels in the Placerville and Auburn districts have yielded exceptional pocket gold. The BLM Folsom Field Office administers federal claims; El Dorado County Recorder handles filing, and the county maintains strict CEQA compliance for surface disturbance.
