NASA Gives California's San Andreas Fault a 3-D Closeup

June 25, 2009
This image showing a portion of the San Andreas Fault along the San Francisco Peninsula was taken by the 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, which provides the primary source of water for San Francisco.
