Special Report 230: Geologic Gems of California State Parks

California is a veritable treasure chest of nationally acclaimed natural landmarks and much adored scenery. This geologic legacy on display in the landscape can be observed throughout California's State Park system. The mission of California State Parks is "to provide for the health, inspiration and education of the people of California by helping to preserve the state's extraordinary biological diversity, protecting its most valued natural and cultural resources, and creating opportunities for high-quality outdoor recreation."We selected exemplary units of the State Park system to highlight California's geologic legacy. The selected parks are dubbed "GeoGems." CGS Special Report 230 is a collection of more than fifty short articles explaining the geologic features of the "GeoGems" for the public.
