Torrey Pines State Nature Reserve

Sandstone rock formations and the rare Torrey Pine tree at Torrey Pines State Nature Reserve in San Diego County, California

Torrey Sandstone is a middle Eocene (48,000,000 years old) rock formation originally deposited as a sandbar. The loose sand was cemented later by calcite from water flowing through the sand. Few fossils are found in the sandstone because not many creatures live in a sand bar.
