Alcatraz Island, San Francisco Bay Fog. San Francisco, California. December 16, 2010. © Copyright G Dan Mitchell – all rights reserved.
Alcatraz Island is almost completely obscured by San Francisco Bay fog drifting beneath blue sky.
This is another of what I sort of think of as my “barely there” photographs, in which I work with subjects that are almost completely obscured by fog, mist, rain, or clouds. Some of my Yosemite Valley photographs from a rainy weekend near the end of this past October are in the same category.
You can experience an astonishing range of atmospheric conditions in and around San Francisco Bay. The patterns at this time of year (the very end of fall, and more like winter conditions) are quite different from summer. As often as not, the fog in the winter comes from inland rather than drifting in through the Golden Gate, and it is more related to the tule fog that can sit in the Central Valley during the winter, sometimes for weeks. On the other hand, after the passage of a winter storm (which brings its own impressive conditions) the winter air over the Bay can be crystal clear. And frequently the conditions can change rapidly, as was the case on this morning. When I arrived in the Marin Headlands above the north end of the Golden Gate Bridge before dawn, I was initially a bit disappointed that the conditions were too clear! Except for a bank of clouds right above San Francisco (the subject of some other recently posted photographs) the rest of the Bay was almost completely clear. But then, at first imperceptibly and then very quickly, fog began to condense out of the air above the bay. In a short period of time subjects that had been clearly visible were completely obscured. Within moments after making this photograph, Alcatraz was not longer visible.
