View north to Salton Sea, CA

View of the Salton Sea and Imperial Valley of California, view northward. The San Andreas takes a right step when it reaches the Salton Sea; transfer of the strain from one part of the fault to the other has caused the area between to be pulled apart. That area is now filled in by the Salton Sea. (ID: 100128-85)
