San Andreas Fault—Tomales Bay - Public Domain image, National Parks Gallery
Summary
Point Reyes National Seashore, California. Tomales Bay is the surface expression of the San Andreas Fault. The granite rocks in the foreground are similar to those found in Yosemite National Park in the Sierra Nevada Mountains. They have been transported about 300 miles (500 kilometers) in a north-northwestward direction along the transform plate boundary. The sedimentary and metamorphic rocks across the fault line are similar to those found in Redwood National and State Parks on the North Coast of California. They were lifted out of the ocean as part of the accretionary wedge of an ancient subduction zone.
