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.
Most of the mountain range is within the Los Padres National Forest, and the northern slopes are included in the remote San Rafael Wilderness area.
The highest peaks include Big Pine Mountain (6,820 ft; 2,080 m), [2] San Rafael Mountain (6,593 ft; 2,010 m) [3] and McKinley Mountain (6,220 ft; 1,900 m), [4] none of which are easily accessible except by foot or horse. The highest peak at the southern edge of the range is Little Pine Mountain.
Hurricane Deck is a spectacular block of sandstone that can be found deep in the San Rafael Wilderness.
The Sisquoc River headwaters are on the north slopes of Big Pine Mountain. It is a designated Wild and Scenic River of the United States, and a tributary of the Santa Maria River. Sisquoc Falls, 250 feet (76 m) high, is located on a tributary of the Sisquoc River to the west of Big Pine Mountain.
Climate is moderate, with hot dry summers (rare thunderstorms) and cool to cold wet winters. Snow sometimes falls on the higher slopes between December and March during frontal passages. Annual precipitation totals are between 15 and 25 inches.
The six highest peaks of the San Rafael Mountains with more than 500 feet (150 m) of prominence, listed by height:
The mountains mainly consist of sedimentary and metamorphic rocks, of Jurassic age or younger, though there are a few regions of igneous intrusions. Several prominent faults exist, including the Big Pine Fault, which trends eastward towards the San Andreas Fault about forty miles away.
The mountains are steep and rugged, and the lower slopes are dominated by chaparral. This ecosystem is naturally adapted to large, high-severity fires every 30 to 100 years or more. [5] Nearly every area within the San Rafael Mountains has burned within the last century, largely due to an increase in human-caused ignitions. [6] In the more shaded and moist canyons and northern slopes oak woodlands, bigcone Douglas-fir, and Coulter pine are found. Gray pine is also interspersed across the chaparral-dominated slopes.
Above the montane chaparral and woodlands ecosystem zone are stands of conifers of the mixed evergreen forest ecosystem. These stands are composed of Jeffrey pine, ponderosa pine, Coulter pine, sugar pine, singleleaf pinyon pine, white fir, and incense cedar. [7] Snow is common in the winter above about 6,000 feet (1,800 m), though overall the climate of the mountain range is Mediterranean, with mild rainy winters and warm, dry summers.
The earliest known residents of the San Rafael Mountains were the Chumash Indians, and evidence of their habitation consists of pictograph rock paintings in remote areas.
In historic times, mercury mining was conducted on portions of the southern slopes. Tailings from these old mines sometimes contain high levels of mercury, and environmental investigations have been conducted to determine if cleanup is necessary and feasible.[ citation needed ]
The central part of the mountains is included into Santa Ynez Recreation area, a part of Los Padres National Forest, and is a popular hiking destination, with a dozen campgrounds. [8]
The Santa Cruz Mountains are a mountain range in central and Northern California, United States, constituting a part of the Pacific Coast Ranges. They form a ridge down the San Francisco Peninsula, south of San Francisco. They separate the Pacific Ocean from the San Francisco Bay and the Santa Clara Valley, and continue south to the Central Coast, bordering Monterey Bay and ending at the Salinas Valley. The range passes through the counties of San Mateo, Santa Clara, and Santa Cruz, with the Pajaro River forming the southern boundary.
The San Gabriel Mountains are a mountain range located in northern Los Angeles County and western San Bernardino County, California, United States. The mountain range is part of the Transverse Ranges and lies between the Los Angeles Basin and the Mojave Desert, with Interstate 5 to the west and Interstate 15 to the east. The range lies in, and is surrounded by, the Angeles and San Bernardino National Forests, with the San Andreas Fault as its northern border.
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 Transverse Ranges is due to their east–west orientation, making them transverse to the general northwest–southeast orientation of most of California's coastal mountains.
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 Sierra Madre is a mountain range in southwestern California. It forms the southernmost part of the California Coast Ranges and lies mostly in Santa Barbara County, with a small portion extending into Ventura County. The Sierra Madre has a northwest-to-southeast orientation, bordered on the north and northeast by the Cuyama River and Cuyama Valley, and on the south and east by the drainage of the Sisquoc River.
The Santa Lucia Mountains or Santa Lucia Range 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.
Junipero Serra Peak is the highest mountain in the Santa Lucia range of central California with a height of 1,785 metres. It is also the highest peak in Monterey County, and is located within the boundaries of Los Padres National Forest. It is named after Saint Junípero Serra, the Spanish Franciscan priest who founded the California Missions in the 18th century. There is a fire lookout, with a tower and building, near the peak that was constructed around 1935. An unauthorized skiing operation on the summit was reported sometime before 1970. Good astronomical observing conditions were an early attraction to the peak. Astronomers scratched a trail to the summit in January 1880 to observe a total eclipse of the sun. Observations from the peak were also made on the transit of Venus in 1882.
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.
Los Padres National Forest is a United States national forest in southern and central California. Administered by the United States Forest Service, Los Padres includes most of the mountainous land along the California coast from Ventura to Monterey, extending inland. Elevations range from sea level to 8,847 feet (2,697 m).
The Verdugo Mountains, also known as the Verdugo Hills or simply The Verdugos, are a small, rugged mountain range of the Transverse Ranges system in Los Angeles County, California. Located just south of the western San Gabriel Mountains, the Verdugo Mountains region incorporates the cities of Burbank, Glendale, Pasadena, and La Cañada Flintridge; the unincorporated communities of Altadena and La Crescenta-Montrose; as well as the City of Los Angeles neighborhood of Sunland-Tujunga.
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 Topatopa Mountains are a mountain range in Ventura County, California, north of Ojai, Santa Paula, and Fillmore. They are part of the Transverse Ranges of Southern California.
The Sisquoc River is a westward flowing river in northeastern Santa Barbara County, California. It is a tributary of the Santa Maria River, which is formed when the Sisquoc River meets the Cuyama River at the Santa Barbara County and San Luis Obispo County border just north of Garey. The river is 57.4 miles (92.4 km) long and originates on the north slopes of Big Pine Mountain, at approximately 6,320 feet (1,930 m). Big Pine Mountain is part of the San Rafael Mountains, which are part of the Transverse Ranges.
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.
Big Pine Mountain is a mountain located in the San Rafael Mountains of the California Transverse Ranges. High enough to receive snowfall during the winter, The summit, at 6800+ feet (2,074+ m), is the highest point in the San Rafael Mountains, the Dick Smith Wilderness, and Santa Barbara County. The peak and the surrounding area were severely impacked by the Zaca fire in 2007.
Pine Mountain Ridge is a massif of the Transverse Ranges located in northern Ventura County, and entirely within the Los Padres National Forest. The ridge is a large block of Matilija Sandstone, and reaches some of the highest elevations in the southern Transverse Ranges. The north slope of the ridge is part of the Sespe Wilderness.
The California montane chaparral and woodlands is an ecoregion defined by the World Wildlife Fund, spanning 7,900 square miles (20,000 km2) of mountains in the Transverse Ranges, Peninsular Ranges, and Coast Ranges of southern and central California. The ecoregion is part of the larger California chaparral and woodlands ecoregion, and belongs to the Mediterranean forests, woodlands, and scrub biome.
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.
Little Pine Mountain is a mountain in Santa Barbara County, California, in the Los Padres National Forest at the southern edge of the San Rafael Mountains. It separates the drainages of Oso Creek, which flows into the upper Santa Ynez River, from the drainage of Santa Cruz Creek, which flows into the middle section of the river via Lake Cachuma. The mountain is named for a thin grove of Coulter pines located on the summit.
