The Rockaway Quarry was a Calera limestone quarry in Pacifica, California, in the San Francisco Bay Area. Limestone from the site was first extracted by Ohlone from the village of Pruristac. Beginning in 1776, New Spaniards used California Indian labor to mine limestone and build structures like the Presidio and San Francisco missions. After the 1906 earthquake, the quarry's limestone was used to rebuild San Francisco. By the 1960s, operations declined, and the quarry permanently closed in 1987. Today it is privately held but is used as an informal hiking trail.
