California: Diverse Geology, Diverse Quarry Products
California's 259 stone quarries reflect the state's remarkable geological diversity, from the Sierra Nevada granite that built San Francisco to the limestone deposits supplying Southern California's cement industry. The Golden State's quarries produce everything from decorative building stone to massive quantities of construction aggregate supporting one of the world's largest economies. Major quarrying regions include the Central Valley, Sierra Nevada foothills, and the coastal ranges, with operations serving the state's substantial residential, commercial, and infrastructure construction sectors. California's strict environmental regulations have shaped the industry toward sustainable practices and reclamation.
