This image showing a portion of the San Andreas Fault along the San Francisco Peninsula was taken by the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument on NASA’s Gulfstream III research aircraft.

The narrow body of water running diagonally along the fault from upper left to lower right is the Crystal Springs Reservoir, a pair of artificial lakes located in the northern Santa Cruz Mountains, which provides the primary source of water for San Francisco.
