Each of the great bridges spanning San Francisco Bay are captured in this near-nadir photo of the San Francisco and Oakland, California, areas. Starting from the south (left in this photo), Dumbarton, San Mateo, Bay, Golden Gate, and San Rafael bridges are seen. Ribbons of run-off induced sediments color the bay, and multi-colored salt-production pens line the southernmost shore.
