In 1854, the route to the San Joaquin Valley shifted away from the Old Tejon Pass route to the Stockton - Los Angeles Road, using the Fort Tejon Pass, and the Grapevine Canyon. The later Butterfield Overland Mail shortened the route to Cow Springs avoiding Mud Springs, skirting Elizabeth Lake to its north westward via the San Andreas Rift to Oakgrove Canyon then north via Pine Canyon to Antelope Valley and westward again to Cow Springs.
