The Santa Cruz Mountains, part of the Pacific Coast Ranges, are a mountain range in central and northern California, United States. 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, Santa Cruz, San Benito and Monterey, with the Pajaro River forming the southern boundary.
The Santa Clara Valley is a geologic trough in Northern California that extends 90 miles south–southeast from San Francisco to Hollister. The longitudinal valley is bordered on the west by the Santa Cruz Mountains and on the east by the Diablo Range; the two coastal ranges meet south of Hollister. The San Francisco Bay borders the valley to the north, and fills much of the northern third of the valley. The valley floor is an alluvial plain that formed in the graben between the San Andreas Fault to the west and the Hayward and Calaveras faults to the east. Within the valley and surrounding the bay on three sides are the urban communities of San Mateo County, Santa Clara County, and Alameda County, while the narrow southern reaches of the valley extend into rural San Benito County to Hollister. In practical terms, the central portion of the Santa Clara Valley is often considered by itself, contained entirely within Santa Clara County.
The Santa Monica Mountains is a coastal mountain range in Southern California, next to the Pacific Ocean. It is part of the Transverse Ranges.

Boney Mountain in Ventura County, California is one of the highest peaks in the Santa Monica Mountains. The prominent mountain visible from Newbury Park, California is 2,825 feet (861 m). It is also known as Boney Peak. The mountain contains four of the highest peaks in the coastal range of the Santa Monica Mountains: Boney Peak, Sandstone Peak, Exchange Peak, and Tri Peaks. The highest summit in the Santa Monica Mountains is Sandstone Peak, situated less than a mile northeast of Boney Peak along the same ridge of volcanic rock. It is the top section of a mass of volcanic rock which solidified around 15 million years ago, and was later uplifted to its dominant position, overshadowing western Conejo Valley. The Chumash Native Americans have a long and deeply spiritual history of interaction at and near the mountain, and the peak is considered a sacred mountain to the Chumash people.
