The San Rafael Mountains are a mountain range in central Santa Barbara County, California, U.S.. 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 highest peaks include Big Pine Mountain (6,820 ft, 2,079 m), San Rafael Mountain (6,593 ft, 2,010 m) and McKinley Mountain (6,220 ft, 1,896 m), none of which are easily accessible except by foot or horse.
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 mountains mainly consist of sedimentary 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 lower slopes are covered with almost impenetrable chaparral, except where it has been burned, an event which occurs naturally in fire ecology every ten or twenty years . Decades of fire suppression, however, have resulted in some areas of brush which have not burned within the last century. The Forest Service occasionally conducts controlled burns to remove areas of high fire hazard and restore ecological balance of the habitat. In the more shaded and moist canyons and northern slopes oak woodlands and Gray pines (Pinus sabiniana ) are found.
Above the montane chaparral and woodlands ecosystem zone are stands of conifers of the mixed evergreen forest ecosystem. Snow is common in the winter on the summits, 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 can still be found by intrepid hikers in the form 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 recent environmental investigations have been conducted to determine if cleanup is necessary and feasible.
