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.
The Los Angeles Ranges: The Los Angeles Ranges, between Santa Barbara and San Diego counties, are a group of small mountain ranges that extend east to west. Because of this general east-west direction, the Los Angeles Ranges are sometimes called the Transverse Ranges. Most mountain ranges in California run generally from north to south. Included in the Los Angeles Ranges are the Santa Ynez, Santa Monica, San Gabriel, and San Bernardino mountains. Sometimes the San Jacinto and Santa Ana Mountains are included as part of the Los Angeles Ranges.
The San Diego Ranges: The San Diego Ranges cover most of San Diego county in the southwestern corner of California. These mountains, sometimes called the Peninsular Ranges, include the Agua Tibia, Laguna, and Vallecito mountains and extend southward into the Mexican peninsula known as Baja California.
Basin and Range Region: The Basin and Range Province contain the southeastern deserts of California.
n the north, much of the area is a lava plateau. This was formed thousands of years ago when the region was flooded with molten lava flowing out of cracks in the earth's surface.
In the south, a good deal of the area is wasteland and includes the Mojave Desert and the Colorado Desert. Death Valley lies near the California-Nevada border and features some of the most inhospitable territory in the world. Some areas of the Basin and Range Region have been made quite productive, however, due to large irrigation projects that have made farming feasible. Two of these areas are the Imperial and the Coachella Valleys near the California border with Mexico.
