The San Joaquin Valley refers to the area of the Central Valley of California that lies south of the Sacramento-San Joaquin Delta in Stockton. The San Joaquin Valley of California stretches from the Tehachapi Mountains north of Los Angeles up to Sacramento. Largely agricultural, the area is some of the most fertile farmland in the world. The San Joaquin Valley can get very foggy in winter, making driving extremely dangerous with visibility of 100 feet and less. On the faster highways such as Interstate 5 and State Route 99, the fog can turn small accidents into smash-ups of dozens of cars.
The isolation and vastness of the San Joaquin Valley, as well as its poverty and need for jobs, have led the state to build numerous prisons in the area. The most notable of these is Corcoran, whose inmates include Charles Manson, Sirhan Sirhan, and Juan Corona. Other correctional facilities in the valley are at Avenal, Chowchilla, Tracy, Delano, Coalinga, and Wasco.
