Plaque showing location of San Andreas Fault in San Mateo County. The San Andreas Fault is a continental right-lateral strike-slip transform fault that extends roughly 1,200 kilometers (750 mi) through the U.S. state of California. [1]
Stretching for 250 kilometers (160 mi), it is the second-longest fault in California, and one of the most prominent geological features in the southern part of the state. It marks the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range ...
The Mendocino Triple Junction is located at the eastern end of the Mendocino Fracture Zone where it approaches Cape Mendocino. The Mendocino Triple Junction (MTJ) is the point where the Gorda Plate, the North American Plate, and the Pacific Plate meet, in the Pacific Ocean near Cape Mendocino in northern California.

The US Geological Survey defines the geographic center of California about 7.1 miles (11.4 km) driving distance from the United States Forest Service office in the Northern Californian city of North Fork, California. Earth scientists typically divide the state into eleven geomorphic provinces with clearly defined boundaries.
