El Dorado County, California: History
The Indigenous nations of the Maidu, Nisenan, Washoe, and Miwok have been located in El Dorado County for thousands of years. The region is notable for being the site of the 1848 discovery that started the California Gold Rush. As a result, the name "El Dorado" was derived from the Spanish word for, "The Gilded One". 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).
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. Route 50 follows the Pony Express route today.

The Caldor Fire started on August 14, 2021, near Little Mountain, south of Pollock Pines in El Dorado County, about two miles (3.2 km) east of Omo Ranch and four miles (6.4 km) south of Grizzly Flats. It initially burned slowly, but exploded in size on August 16 due to high winds. By the night of August 16, it was 6,500 acres (2,600 ha). On August 17, the fire grew to 30,000 acres (12,000 ha) as it expanded rapidly north and east, crossing the North Fork Cosumnes River and approaching Sly Park Reservoir. By August 20, the fire had burned nearly to U.S. Route 50, forcing a closure of the highway. Over the next few days, the fire crossed Highway 50 in the vicinity of Kyburz. Starting on August 27, winds drove the fire rapidly east towards the Lake Tahoe Basin. By August 30, it had reached Echo Summit, less than five miles (8.0 km) from South Lake Tahoe.
There are only two municipalities in El Dorado County: Placerville and South Lake Tahoe.
