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.

Hardcopies of the Geological Gems of California State Parks can be purchased from the CGS library. The hardcopy book includes two plates folded in a back cover pocket and costs $60.00. The plates can be purchased separately as rolled posters and are available for $10.00 for each of the two plates ($20 for both).
