San Antonio Valley, California facts for kids
The community of San Antonio Valley, also called San Antonio or San Antone, is located along the Diablo Range in eastern Santa Clara County, California. The locale is bordered by Alameda County to the north and Stanislaus County to the east. The sparsely populated area is located at the junction of San Antonio Valley Road, Mines Road, and Del Puerto Canyon Road. The area includes the San Antonio Valley Ecological Reserve, a 3,282 acre nature preserve created by a Nature Conservancy purchase of land from local rancher, Keith Hurner, and known for its herd of tule elk.
History and variant names
The San Antonio Valley appears to have been a transitional area between the native Ohlone cultures from the San Francisco-Monterey region and the Yokut of the San Joaquin River watershed. The Ohlone are speculated to have arrived in the Bay Area around 500 A.D. when they displaced Hokan speaking populations already in the region.
On April 5, 1776, the de Anza Expedition called the area El Cañada de San Vicente. The 1956 Thomas Brothers map spells it San Antone. This spelling mimics the way it is pronounced in common, modern usage by locals. It was spelled San Antone on the 1924 "Mount Boardman, California" U.S. Geological Survey 15-minute quadrangle.
The U.S. Postal Service established a Deforest Post Office in the area during 1892. It was moved within the area in 1897, 1906, and finally closed in 1909. Another 1924 map calls a group of buildings along San Antonio Creek, Deforest. The name comes from Ransford S. Deforest, the first Postmaster in the community.
The community lies in the San Antonio Valley, at elevation 2,133 feet (650 m). The ZIP Code is 94550. The valley is traversed by San Antonio Creek, which flows northwesterward to Arroyo Valle, part of the Alameda Creek watershed.
Sphere of influence
The area is within the sphere of influence of three different counties. The flattest and easiest drive to town is via Mines Road to Livermore in Alameda County. Del Puerto Canyon Road leads 20- to 25-miles east to the area of Interstate 5 and the Stanislaus County community of Patterson. The steepest route out, San Antonio Road, climbs west toward University of California, Lick Observatory, topping out at around 4,200 ft (1,280 m). There it turns into State Route 130 and descends into San Jose in Santa Clara County.
The community includes a CAL FIRE station at 47405 Mines Road. The station is called, Sweetwater - Station 25 and is part of the Santa Clara Ranger Unit, (Firescope mutual aid identifier SCU).
There is a restaurant at the junction of the three roads (Mines, San Antonio Valley, Del Puerto Canyon), appropriately called The Junction Bar and Grill. This restaurant serves as a community center as well as a stopping-off point for the many motorcycles, bicycles, and tourists that travel the roads.
The area was served by manual telephone service until deregulation forced the arrival of dial service in the early 1980s. Prior to this, a non-dial Western Electric 1A1 coin telephone served on San Antonio Road about one mile east of the Observatory. Its telephone number was San Antonio California Toll Station Number 3. Today, wired telephone numbers for the area follow the format (408) 897-xxxx. The telephone utility serving this area today is Frontier Communications.
