The setting sun illuminates the beautiful rocky shore at California’s Montaña de Oro State Park. Millions of years ago, the sedimentary rock of the Montana de Oro coast was an ancient sea floor. When tiny fragments of once-living organisms drifted to the bottom of the sea, they mixed with silt and sand, forming mudstone over time. The mud then solidified into thick layers of sedimentary rock, and now forms the rocky, striated coast at Montaña de Oro.
