Keyhole Arch Sea Arch
Pt. Reyes National Seashore is about 30 miles north of San Francisco. It has the distinction of being the location where the San Andreas Fault says goodbye to the mainland and heads out to sea.. Tomales Bay lies right on the Fault and was formed when land split away from the mainland. This sea arch lies just off the northernmost tip of Point Tomales.
