The Transverse Ranges are a group of mountain ranges of southern California, in the Pacific Coast Ranges physiographic region in North America. The Transverse Ranges begin at the southern end of the California Coast Ranges and lie within Santa Barbara, Ventura, Los Angeles, San Bernardino, Riverside and Kern counties. The Peninsular Ranges lie to the south. The name is due to the ranges' east–west orientation, making them transverse to the general northwest–southeast orientation of most of California's coastal mountains.
San Gorgonio Mountain, also known locally as Mount San Gorgonio, or Old Greyback, is the highest peak in Southern California and the Transverse Ranges at 11,503 feet (3,506 m).
The Santa Ynez Mountains are a portion of the Transverse Ranges, part of the Pacific Coast Ranges of the west coast of North America. It is the westernmost range in the Transverse Ranges.
The San Rafael Mountains are a mountain range in central Santa Barbara County, California, U.S., separating the drainages of the Santa Ynez River and the Santa Maria River. They are part of the Transverse Ranges system of Southern California which in turn are part of the Pacific Coast Ranges system of western North America.
The Santa Lucia Range or Santa Lucia Mountains is a rugged mountain range in coastal central California, running from Carmel southeast for 140 miles (230 km) to the Cuyama River in San Luis Obispo County. The range is never more than 11 miles (18 km) from the coast. The range forms the steepest coastal slope in the contiguous United States. Cone Peak at 5,158 feet (1,572 m) tall and three miles (5 km) from the coast, is the highest peak in proximity to the ocean in the lower 48 United States. The range was a barrier to exploring the coast of central California for early Spanish explorers.
Black Mountain is a summit on Monte Bello Ridge in the Santa Cruz Mountains of west Santa Clara County, California, south of Los Altos and Los Altos Hills, and west of Cupertino; it is within the Palo Alto city limits though not near the developed part of the city. It is located on the border between Rancho San Antonio Open Space Preserve and Monte Bello Open Space Preserve, with the summit located in the former. Early Spanish explorers commonly named tree- or chaparral-covered summits which look black in the distance Loma Prieta, from the Spanish . The Spanish also called the middle portion of the Santa Cruz Mountains the Sierra Morena meaning, extending from Half Moon Bay Road south to a gap at Lexington Reservoir, and which includes a summit called Sierra Morena. There are over 100 "Black Mountains" in California.
The Coast Ranges of California span 400 miles (644 km) from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains.
The Angeles Forest Highway is a 25-mile (40 km) road over the San Gabriel Mountains in Los Angeles County, California. It connects the Los Angeles Basin with the Antelope Valley and western Mojave Desert. Maintained by the Los Angeles County Department of Public Works, the highway is designated as County Route N-3 (CR N-3) or Forest Highway 59 (FH 59); the route numbers are unsigned, but noted on many maps.
The San Rafael Wilderness is a wilderness area in the mountains of north central Santa Barbara County, California, United States. It is north of the city of Santa Barbara and east of Santa Maria within the Los Padres National Forest. Formed in 1968, it was the first wilderness area to be created from a previously designated Primitive Area after the passage of the 1964 Wilderness Act. It also includes the Sisquoc Condor Sanctuary, created in 1937, which is the oldest designated sanctuary for the large endangered birds.
The Dick Smith Wilderness is a wilderness area in the mountains of eastern Santa Barbara County, California, United States, with a portion in Ventura County. It is completely contained within the Los Padres National Forest, and is northeast of the city of Santa Barbara and north of the city of Ojai. It is most easily accessible from two trailheads off State Route 33, which runs north from Ojai. It is adjacent to the large San Rafael Wilderness on the west and the Matilija Wilderness on the south. Across Highway 33 to the east, and also in the Los Padres National Forest, is the large Sespe Wilderness.
Simi Valley is a synclinal valley in Southern California in the United States. It is an enclosed or hidden valley surrounded by mountains and hills. It is connected to the San Fernando Valley to the east by the Santa Susana Pass and the 118 freeway, and in the west the narrows of the Arroyo Simi and the Reagan Freeway connection to Moorpark. The relatively flat bottom of the valley contains soils formed from shales, sandstones, and conglomerates eroded from the surrounding hills of the Santa Susana Mountains to the north, which separate Simi Valley from the Santa Clara River Valley, and the Simi Hills.
The Sespe Formation is a widespread fossiliferous sedimentary geologic unit in southern and south central California in the United States. It is of nonmarine origin, consisting predominantly of sandstones and conglomerates laid down in a riverine, shoreline, and floodplain environment between the upper Eocene Epoch through the lower Miocene. It is often distinctive in appearance, with its sandstones weathering to reddish-brown, maroon, pinkish-gray, tan, and green. Since many of its sandstones are more resistant to erosion than many other regional sedimentary units it often forms dramatic outcrops and ridgelines in many local mountain ranges.
The Rincon Formation is a sedimentary geologic unit of Lower Miocene age, abundant in the coastal portions of southern Santa Barbara County, California eastward into Ventura County. Consisting of massive to poorly bedded shale, mudstone, and siltstone, it weathers readily to a rounded hilly topography with clayey, loamy soils in which landslides and slumps are frequent. It is recognizable on the south slopes of the Santa Ynez Mountains as the band at the base of the mountains which supports grasses rather than chaparral. Outcrops of the unit are infrequent, with the best exposures on the coastal bluffs near Naples, in the San Marcos Foothills, at the Tajiguas Landfill, and in road cuts. The geologic unit is notorious as a source of radon gas related to its high uranium content, released by radioactive decay.
The Cozy Dell Shale is a geologic formation of middle Eocene age that crops out in the Santa Ynez Mountains and Topatopa Mountains of California, extending from north of Fillmore in Ventura County westward to near Point Arguello, north of Santa Barbara. Because the Cozy Dell easily weathers to a clay-rich soil, it crops out infrequently and generally forms dense stands of chaparral in saddles between peaks and ridges of the more resistant Matilija and Coldwater formations.
The Coldwater Sandstone is a sedimentary geologic unit of Eocene age found in Southern California, primarily in and south of the Santa Ynez Mountains of Santa Barbara County, and east into Ventura County. It consists primarily of massive arkosic sandstone with some siltstone and shale. Being exceptionally resistant to erosion, outcrops of the Coldwater form some of the most dramatic terrain on the south slope of the Santa Ynez Mountains, with immense white sculpted slabs forming peaks, hogback ridges, and sheer cliff faces.
The Matilija Sandstone is a sedimentary geologic unit of Eocene epoch in the Paleogene Period, found in Santa Barbara and Ventura Counties in Southern California.
The Juncal Formation is a prominent sedimentary geologic unit of Eocene age found in and north of the Santa Ynez Mountain range in southern and central Santa Barbara County and central Ventura County, California. An enormously thick series of sediments deposited over millions of years in environments ranging from nearshore to deep water, it makes up much of the crest of the Santa Ynez range north of Montecito, as well as portions of the San Rafael Mountains in the interior of the county. Its softer shales weather to saddles and swales, supporting a dense growth of brush, and its sandstones form prominent outcrops.
The Jalama Formation is a sedimentary rock formation widespread in southern Santa Barbara County and northern Ventura County, southern California. Of the Late Cretaceous epoch, the unit consists predominantly of clay shale with some beds of sandstone.
The Espada Formation is a sedimentary rock formation widespread in Santa Barbara County, California. Of late Jurassic to Cretaceous age, the unit consists primarily of shale with some interbedded thin layers of sandstone, conglomerate, and limestone.
The Santa Cruz Trail is a trail in the Los Padres National Forest, in Santa Barbara County, California. It is the primary footpath from the Santa Ynez Recreation Area into the San Rafael and Dick Smith Wilderness areas. The section from the southern trailhead up to Santa Cruz Camp is designated as the Santa Cruz - Aliso National Recreation Trail.
