Earthquake Trail, Point Reyes National Seashore, California


ID 2982

The 0.5-mile Earthquake Trail near the Bear Valley Visitor Center has a number of displays describing California geology, plate tectonics, and the San Andreas fault. During the Great San Francisco Earthquake of 1906, the San Andreas fault ruptured the ground for a distance of about 270 miles. Ground movement caused displacement of fences, roads, railroad tracks, and buildings. The National Park Service reconstructed this fence along the Earthquake Trail to show 16 feet of offset that was recorded in this area. The fence on the right hand side moved toward the northwest in the same direction as the Pacific Plate and the fence on the left side moved toward the southeast in the same direction as the North American Plate.
