Fog, San Francisco Skyline and Crepuscular Rays
November 19, 2009
Fog is not and infrequent visitor to the San Francisco Bay area. It creeps in not just on “little cat feet” but also sweeps in as advection fog from the west and northwest during the summer season. See also the Earth Science Picture of Day for September 23, 2009. The above photo was taken during the early morning of September 26, 2009, from Alexander Drive in the Marin Headlands. Bay Bridge is in the far background, at left, and is outside of the fog area. The San Francisco skyline is also in the background. Golden Gate Bridge is in the mid-ground and has just popped out of the fog. Crepuscular rays, lower left foreground, filter through the translucent canopy and into the foggy abyss below.
