County Flag


The present-day site of El Dorado County was once home to the Maidu, Washoe, and Miwok Native American tribes, and is notable for being the site of the 1848 gold discovery that sparked the California Gold Rush.[6] The County of El Dorado was one of California’s original 27 counties created effective February 18, 1850 (the number has risen to 58 today). Its name is derived from the Spanish meaning “the gilded/golden”.[7]

The final segments of the Pony Express mail route ran through El Dorado County until its replacement with the telegraph service in 1861; U.S. Highway 50 follows the Pony Express route today.
