The Santa Cruz Mountains, part of the Pacific Coast Ranges, are a mountain range in central California, United States. They form a ridge along the San Francisco Peninsula, south of San Francisco, separating the Pacific Ocean from San Francisco Bay and the Santa Clara Valley, and continuing south, bordering Monterey Bay and ending at the Salinas Valley. The range passes through San Mateo, Santa Clara and Santa Cruz counties, with the Pajaro River forming the southern boundary. The northernmost portion of the Santa Cruz Mountains is known as Montara Mountain, north of Half Moon Bay Road (California State Route 92) the middle portion is known as the Sierra Morena, which includes a summit called Sierra Morena, and extends south to a gap at Lexington Reservoir, south of the gap the mountain range is known as the Sierra Azul. The highest point in the range is Loma Prieta Peak , near which is the epicenter of the 1989 Loma Prieta earthquake. Other major peaks include Mount Umunhum , Mount Bielawski , El Sombroso , Eagle Rock , Black Mountain , and Sierra Morena . The San Andreas Fault runs along or near the ridge line throughout the range. The east side of the mountains drops abruptly towards this fault line especially near Woodside and Saratoga. For much of the length of the range on the San Francisco Peninsula, State Route 35 runs along its ridge, and is known as "Skyline Boulevard". The major routes across the mountains are (from north to south) SR 92 from Half Moon Bay to San Mateo, SR 84 from San Gregorio to Redwood City, SR 9 from Santa Cruz to Saratoga, SR 17 from Santa Cruz to Los Gatos, SR 152 from Watsonville to Gilroy, SR 129 from Watsonville to San Juan Bautista, and US Highway 101 from Salinas to Gilroy. The Santa Cruz Mountains have been a legally defined American Viticultural Area since 1981. Wine has been produced here since at least the 1840s. The Santa Cruz Mountain AVA has emerged as premier producer of top wines, recognized in the historic Judgment of Paris on May 26, 1976.〔 〕 There are over 30 wineries located in this area. ==Geology== The Santa Cruz Mountains are largely the result of compressive uplift caused by a leftward bend of the San Andreas Fault. The Salinian Block basement rocks are overlain by Miocene rock strata of the Lompico Sandstone, the Vaqueros Sandstone and the Santa Margarita Formation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Santa Cruz Mountains」の詳細全文を読む スポンサード リンク
