The Tejon Pass, previously known as Portezuelo de Cortes, Portezuela de Castac, and Fort Tejon Pass is a mountain pass between the southwest end of the Tehachapi Mountains and northeastern San Emigdio Mountains, linking Southern California north to the Central Valley. Both the pass and the grade north of it to the Central Valley are commonly referred to as "the Grapevine". It has been traversed by major roads such as the El Camino Viejo, the Stockton – Los Angeles Road, the Ridge Route, U.S. Route 99, and now Interstate 5.
The Ridge Route, officially the Castaic–Tejon Route and colloquially known as the Grapevine, was a two-lane highway between Los Angeles County and Kern County, California. Opened in 1915 and paved with concrete between 1917 and 1921, the road was the first paved highway directly linking the Los Angeles Basin with the San Joaquin Valley over the Tejon Pass and the rugged Sierra Pelona Mountains ridge south of Gorman. Much of the old road runs through the Angeles National Forest, and passes many historical landmarks, including the National Forest Inn, Reservoir Summit, Kelly's Half Way Inn, Tumble Inn, and Sandberg's Summit Hotel. North of the forest, the Ridge Route passed through Deadman's Curve before ending at Grapevine.
Gorman is an unincorporated community in northwestern Los Angeles County, California, United States. It is located in Peace Valley south of the Tejon Pass, which links Southern California with the San Joaquin Valley and Northern California. Due to this location, the area has served as a historic travel stop dating back to the indigenous peoples of California. Tens of thousands of motorists travel through Gorman daily on the Golden State Freeway since the highway's completion in the mid-20th Century.
Grapevine is an unincorporated community in Kern County, California, United States, at the southern end of the San Joaquin Valley.

Fort Tejon in California is a former United States Army outpost which was intermittently active from June 24, 1854, until September 11, 1864. It is located in the Grapevine Canyon between the San Emigdio Mountains and Tehachapi Mountains. It is in the area of the Tejon Pass along Interstate 5 in Kern County, California, the main route through the mountain ranges separating the Central Valley from the Los Angeles Basin and Southern California. The fort's location protected the San Joaquin Valley from the south and west.
State Route 223, locally known as Bear Mountain Boulevard, is a state highway in the U.S. state of California that runs west to east through the agricultural land south of Bakersfield in Kern County. Running from Interstate 5 (I-5) to State Route 58 near the city of Arvin, it also intersects with State Route 99 near Greenfield. SR 223 forms a truck route for transporting goods to the three main corridors in the area, I-5, SR 58 and SR 99, without having to drive through Bakersfield.
The White Wolf Fault is a fault in southern California, located along the northwestern transition of the Tejon Hills and Tehachapi Mountains with the San Joaquin Valley. It is north of the intersection of the San Andreas Fault and the Garlock Fault, and roughly parallel with the latter. It is classed as a reverse fault with a left lateral (sinistral) component.
Interstate 5 (I-5) is a major north–south route of the Interstate Highway System in the United States, running largely parallel to the Pacific Coast between the Mexican border and the Canadian border. The segment of I-5 in California runs across the length of the state from the Mexican border at the San Ysidro Port of Entry in the San Ysidro neighborhood of San Diego to the Oregon state line south of the Medford-Ashland metropolitan area. It is the longest interstate in California at 796.77 miles (1,282.28 km), and accounts for more than half of I-5's total length of 1,381.29 miles (2,222.97 km). It is also the second longest stretch of Interstate Highway with a single designation within a single state after I-10 in Texas.
The 1952 Kern County earthquake occurred on July 21 in the southern San Joaquin Valley and measured 7.3 on the moment magnitude scale. The main shock occurred at 4:52 am Pacific Daylight Time, killed 12 people, injured hundreds more and caused an estimated $60 million in property damage. A small sector of damage near Bealville corresponded to a maximum Mercalli intensity of XI (Extreme), though this intensity rating was not representative of the majority of damage. The earthquake occurred on the White Wolf Fault near the community of Wheeler Ridge and was the strongest to occur in California since the 1906 San Francisco earthquake.
The Tejon Hills are a low mountain range in the Transverse Ranges, in southern Kern County, California. The highest point of the hills is Comanche Mountain, at 364 feet (111 m) in elevation.
Kern County’s transportation system was quoted as the “unseen industry.” Located at the southern end of the San Joaquin Valley, the county is at a prime location to ship goods west to the central coast, south to ports in Los Angeles, and east to corridors that connect to the rest of the country. It is also on major corridors that link to all northern points.
