Several natural features are captured in this photo below of the San Francisco Bay Area—the Montara Mountains and Cahill Ridge that abut the San Andreas Fault, upon which lie San Andreas Lake and elongated Crystal Springs Reservoir; and Alcatraz Island and Treasure Island, north and north-northeast, respectively, of downtown San Francisco. Discernible are three major bridges (San Mateo, San Francisco-Oakland Bay, and Golden Gate) that connect the cities surrounding San Francisco Bay; the intersecting runways of San Francisco International Airport along the west side of the bay; and dark, elongated Golden Gate Park south of the Golden Gate Bridge.
