Coastal Ranges: The Coastal Ranges in the north reach inland 20 to 30 miles extend from the Klamath Mountains in the north south to Santa Barbara. The Coastal Ranges include many smaller chains of mountain ranges including the Diablo and Santa Cruz Mountains. Some of the valleys separating these ranges are the Napa Valley, north of San Francisco and the Santa Clara and Salinas Valleys to the south. The Coastal Range is home to California's legendary Redwoods and, less fortunately the San Andreas Fault. The San Andreas Fault enters California from the Pacific Ocean near Port Arena and extends southeast into the state. Earthquakes are caused by movement of the earth's crust along this fault.
The Sierra Nevada: The Sierra Nevada mountain range in the east runs about 430 miles from north to south and forming a giant wall rising to over 14,000 feet. The range varies from around 40 to 70 miles wide. Many peaks in the range reach over 14,000 feet above sea level, with Mt. Whitney, at 14,494 feet, the highest peak in the United States south of Alaska. Mountain streams and glacial action have cut deep valleys into the western part of the Sierras. Yosemite Valley is one of the most spectacular of these valleys. Visit the Sierra Nevadas at the United States Geological Survey.
Central Valley: The Central Valley lies between the Coastal Range and the Sierra Nevada range and is home to the San Joaquin and Sacramento rivers. Sometimes called the Great Valley, the Central Valley is about 450 miles long from points in the northwest to the southeast. A level, broad fertile plain, the Central Valley is the most important farming area west of the Rocky Mountains and comprises about three-fifths of California's productive farmland.
Cascade Mountains: The Cascade Mountains extend north from the Sierra Nevada mountain range. They were formed by volcanoes unlike the other mountain ranges in California and support one still-active volcano; Lassen Peak. Lassen is 10,457 feet high and located in the southern Cascades. The Cascade Mountains are also home to Mt. Shasta, once and active volcano. Mt. Shasta rises 14,162 feet above sea level.
