Tehachapi Pass (Kawaiisu: Tihachipia, meaning "hard climb") [2] [3] is a mountain pass crossing the Tehachapi Mountains in Kern County, California. Traditionally, the pass marks the northeast end of the Tehachapis and the south end of the Sierra Nevada range.
The route is a principal connector between the San Joaquin Valley and the Mojave Desert. The Native American Kitanemuk people used the pass as a trade route before the American settlement of the region in the 19th century. The main line of the former Southern Pacific Railroad opened though the pass in 1876; [4] the tracks are now owned by the Union Pacific Railroad and shared with BNSF Railway. U.S. Route 466 was built in the 1930s, and the road is now State Route 58. The Pass is also the route of the planned California High-Speed Rail line.
The Tehachapi Mountains are also crossed by Tejon Pass at the southwest end of the range.
The precise meaning of the name Tehachapi Pass is often a source of confusion. Technically (i.e., as noted on USGS topographic maps), the name refers to the narrowest part of the canyon on the eastern approach to the summit (as at San Gorgonio Pass), where the elevation is about 3,771 feet (1,149 m). [1] The actual high point is just east of the town of Tehachapi, at an elevation (on the railroad next to Tehachapi Boulevard) of 4,031 feet (1,229 m). [1] The highway sign refers to this location as Tehachapi Summit. However, the term Tehachapi Pass is routinely used to refer to both this location and the approaches on either side.
The mountain pass acts as a venturi effect to air moving between ocean and desert, increasing wind speed. [5]
The area east and south of the pass is home to the Tehachapi Pass Wind Farm, and to the west is Alta Wind Energy Center, some of California's larger wind farms.
The railroad landmark known as the Tehachapi Loop is about 18 miles (29 km) west of the summit. The pass is also a proposed route for the California High-Speed Rail line between Palmdale and Bakersfield. [6]
California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the major geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states. The state is generally divided into Northern and Southern California, although the boundary between the two is not well defined. San Francisco is decidedly a Northern California city and Los Angeles likewise a Southern California one, but areas in between do not often share their confidence in geographic identity. The US Geological Survey defines the geographic center of the state at a point near North Fork, California.
Tehachapi is a city in Kern County, California, United States, in the Tehachapi Mountains, at an elevation of 3,970 feet (1,210 m), between the San Joaquin Valley and the Mojave Desert. Tehachapi is 35 miles (56 km) east-southeast of Bakersfield, and 20 miles (32 km) west of Mojave. According to the United States Census Bureau, the city has a total area of 10 square miles (26 km2) and a population of 14,414. The Tehachapi area is known for the nearby Tehachapi Loop, the Pacific Crest Trail and for the excellent conditions for the aerial sport of gliding.
State Route 14 is a north–south state highway in the U.S. state of California that connects Los Angeles to the northern Mojave Desert. The southern portion of the highway is signed as the Antelope Valley Freeway. The route connects Interstate 5 on the border of the city of Santa Clarita to the north and the Los Angeles neighborhoods of Granada Hills and Sylmar to the south, with U.S. Route 395 (US 395) near Inyokern. Legislatively, the route extends south of I-5 to SR 1 in the Pacific Palisades area of Los Angeles; however, the portion south of the junction with I-5 has not been constructed. The southern part of the constructed route is a busy commuter freeway serving and connecting the cities of Santa Clarita, Palmdale, and Lancaster to the rest of the Greater Los Angeles area. The northern portion, from Vincent to US 395, is legislatively named the Aerospace Highway, as the highway serves Edwards Air Force Base, once one of the primary landing strips for NASA's Space Shuttle, as well as the Naval Air Weapons Station China Lake that supports military aerospace research, development and testing. This section is rural, following the line between the hot Mojave desert and the forming Sierra Nevada mountain range. Most of SR 14 is loosely paralleled by a rail line originally built by the Southern Pacific Railroad, and was once the primary rail link between Los Angeles and Northern California. While no longer a primary rail line, the southern half of this line is now used for the Antelope Valley Line of the Metrolink commuter rail system.
The Tehachapi Mountains are a mountain range in the Transverse Ranges system of California in the Western United States. The range extends for approximately 40 miles (64 km) in southern Kern County and northwestern Los Angeles County and form part of the boundary between the San Joaquin Valley and the Mojave Desert.
The Tehachapi Loop is a 3,779-foot-long spiral, or helix, on the Union Pacific Railroad Mojave Subdivision through Tehachapi Pass, of the Tehachapi Mountains in Kern County, south-central California. The line connects Bakersfield and the San Joaquin Valley to Mojave in the Mojave Desert.
Donner Pass is a 7,056-foot-high (2,151 m) mountain pass in the northern Sierra Nevada, above Donner Lake and Donner Memorial State Park about 9 miles (14 km) west of Truckee, California. Like the Sierra Nevada themselves, the pass has a steep approach from the east and a gradual approach from the west.
Altamont Pass, formerly Livermore Pass, is a low mountain pass in the Diablo Range of Northern California between Livermore in the Livermore Valley and Tracy in the San Joaquin Valley. The name is actually applied to two distinct but nearby crossings of the range. The lower of the two, at an elevation of 741 ft (226 m), carries two railroad rights-of-way (ROWs) and Altamont Pass Road, part of the old Lincoln Highway and the original alignment of US 50 before it was bypassed c. 1937. The bypass route travels over the higher summit, at 1,009 ft (308 m), and now carries Interstate 580, a major regional highway heavily congested by Central Valley suburbanization.
Cajon Pass is a mountain pass between the San Bernardino Mountains to the east and the San Gabriel Mountains to the west in Southern California. Created by the movements of the San Andreas Fault, it has an elevation of 3,777 ft (1,151 m). Located in the Mojave Desert, the pass is an important link from the Greater San Bernardino Area to the Victor Valley, and northeast to Las Vegas. The Cajon Pass area is on the Pacific Crest Trail.
Soledad Canyon is a long narrow canyon/valley located in Los Angeles County, California between the cities of Palmdale and Santa Clarita. It is a part of the Santa Clara River Valley, and extends from the top of Soledad Pass to the open plain of the valley in Santa Clarita. The upstream section of the Santa Clara River runs through it.
Caliente is an unincorporated community in Kern County, California. It is located 22 miles (35 km) east-southeast of Bakersfield, at an elevation of 1,312 feet (400 m).
The Diablo Range is a mountain range in the California Coast Ranges subdivision of the Pacific Coast Ranges in northern California, United States. It stretches from the eastern San Francisco Bay area at its northern end to the Salinas Valley area at its southern end.
The San Gorgonio Pass, or Banning Pass, is a 2,600 ft (790 m) elevation gap on the rim of the Great Basin between the San Bernardino Mountains to the north and the San Jacinto Mountains to the south. The pass was formed by the San Andreas Fault, a major transform fault between the Pacific plate and the North American plate. The tall mountain ranges on either side of the pass result in the pass being a transitional zone from a Mediterranean climate west of the pass, to a Desert climate east of the pass. This also makes the pass area one of the windiest places in the United States, and why it is home to the San Gorgonio Pass wind farm.
Siskiyou Pass is a historic mountain pass in the Siskiyou Mountains of Jackson County. It is the most used pass in the U.S. state of Oregon. The Hudson's Bay Company (HBC) made the Siskiyou Trail over the pass before pioneers traversed it with their wagons, while still later it evolved into a stage road, a railroad line, and a highway route. The name Siskiyou is believed to be derived from Cree, meaning "bob-tailed horse". Siskiyou Pass is west of the summit of Interstate 5, which is known as Siskiyou Summit.
The Pequop Mountains are a mountain range located in eastern Elko County, in northeastern Nevada in the western United States. The range runs generally north-south for approximately 51 miles (82 km) The high point of the range is an unnamed peak located at 40°55.46'N and 114°35.38'W.
Siskiyou Summit is a summit on Interstate 5 (I-5) in the U.S. state of Oregon. It is distinct from Siskiyou Pass, which is a nearby, historical mountain pass. Siskiyou Summit is situated in the Siskiyou Mountains, approximately 4 miles (6.4 km) north of the California border. At 4,310 feet (1,310 m), it is the highest point on Interstate 5. When the highway was rebuilt on its current alignment, road cutting lowered the elevation of the summit by 49 feet (15 m).
U.S. Route 395 (US 395) is a United States Numbered Highway, stretching from Hesperia, California to the Canadian border in Laurier, Washington. The California portion of US 395 is a 557-mile (896 km) route which traverses from Interstate 15 (I-15) in Hesperia, north to the Oregon state line in Modoc County near Goose Lake. The route clips into Nevada, serving the cities Carson City and Reno, before returning to California.
Sherman is a ghost town in Albany County, Wyoming, United States. Sherman is 19 miles (31 km) southeast of Laramie in the Laramie Mountains and is named for Civil War general William Tecumseh Sherman, purportedly at his request. From the 1860s to 1918, the town sat at the summit of the original grade of the first transcontinental railroad along the rails of the Union Pacific Railroad, at an elevation of 8,247 ft (2,514 m).
Soledad Pass, elevation 3,209 ft (978 m), is a mountain pass in northern Los Angeles County, California.
The California High-Speed Rail system will be built in two phases. Phase 1 will be about 520 miles (840 km) long, and is planned to be completed in 2033, connecting the downtowns of San Francisco and Los Angeles using high-speed rail through the Central Valley with feeder lines served at Merced and an extension to Anaheim. In Phase 2, the route will be extended in the Central Valley north to Sacramento, and from east through the Inland Empire and then south to San Diego. The total system length will be about 800 miles (1,300 km) long. Phase 2 currently has no timeline for completion.
