Corral Hollow, formed by Corral Hollow Creek, is a canyon partially located in Alameda County, with parts in San Joaquin County, 6.5 miles (10.5 km) southwest of Tracy, California. Corral Hollow Creek, formerly El Arroyo de los Buenos Ayres (The Creek of the Good Winds), from its source 1.9 miles (3.1 km) north of Mount Boardman, flows north 1.89 miles where it turns to flow west-northwest 8.5 miles (13.7 km) then turns abruptly east in the vicinity of Tesla to flow 5 miles (8.0 km) east where it turns again in a northeasterly direction for 6 miles (9.7 km) to the Delta-Mendota Canal in the San Joaquin Valley. It was occupied by Native Americans prior to European contact, and is within both Yokuts and Ohlone ancestral homelands. El Camino Viejo, an old Spanish colonial trail, passed through the valley, which was part of the routes of both Spanish and Mexican cattle-drivers, and gold-diggers during the Californian Gold Rush. Later, it was the site of the coal-mining town of Tesla, and Carnegie, which mined clay, both of which were destroyed by a flood in 1911. Around 2001, the California government purchased an area of land around Tesla in order to allow off-road vehicles, which was protested by ecological organizations until the state passed a law banning that usage of the land in 2022.
