The lights on the Golden Gate Bridge have just been switched off and a pregnant day promises to deliver as the first rays of the Sun are about to pierce the skies over San Francisco.
I shot this image on an early Saturday morning from the Marin Headlands. I was perhaps the only person on Hawk Hill on this morning, a former World War II bunker built in the park to defend against battleships. It was there that after Pearl Harbor anti-aircraft guns were installed and radar stations were developed. During the Cold War, the Nike Defence system was put into place in the Bay Area. It is also a great place for Raptor watching. Hawks, kites, falcons, eagles, vultures, ospreys and harriers can be found flying overhead, hence the name Hawk Hill.
