Offset Streams

Photo: Offset streams at Carrizo Plain
Offset streams cut into the Carrizo Plain along the San Andreas Fault in California. The fault, which runs more than 700 miles (1,100 kilometers), is the boundary between the Pacific and North American tectonic plates. The stretch of the fault that runs through Carrizo Plain is very well defined because the land is arid and the fault has not been significantly eroded.
