I love fog, and I especially love the thick and mysterious tule fog of California’s Central Valley — comprised of the northern Sacramento Valley and the southern San Joaquin Valley, and draining to the Pacific Ocean via San Francisco Bay. This fog is mostly a winter thing, when the moisture rises from the ground, farmland, and ponds as the temperature drops at night. It often reaches its peak in the early morning, just after dawn. (It also creates some very challenging driving conditions — so bad that lots of people simply try to avoid them.)

If you stop and get out of your car, the world of tule fog is quiet and mysterious and still. Your universe closes down to a radius of perhaps a couple hundred feet or less, and you can sense as much about your surroundings by sound as you can by vision — you might hear but not see a flock of crane passing overhead. Surprising to some who are new to these conditions, while the tule fog is incredibly dense, it is often astonishingly shallow. On occasion I have seen conditions so bad that it was almost impossible to drive… but I could look up and see clouds in the sky overhead. The tops of trees and utility poles might poke out of the top of the fog layer. This, of course, can produce some very special light, since this thick fog may also be intensely illuminated by that overhead sky and sun, to the point that at times it can almost hurt to look into the brightness. Those were not the conditions when I made this photograph, but the astonishing blue color (which I actually had to tone down a bit in post) is the result of the glowing fog picking up the color of the blue morning sky.

A bare winter tree and clearing tule fog.

On Sunday there was ground fog all over the San Francisco Bay Area, and I had a few free hours, so I headed out to see what I could find. I went to a place that is very familiar to me, a local haunt where I have hiked and photographed for decades. I had not been there in perhaps a year, so it was good to reestablish my relationship with the location and note a few changes. The little trip also reminded me that it isn’t necessary to travel long distances to find photographic subjects — quite often a closer look at nearby places will reveal worthy subjects.

The idea here was to arrive before the fog cleared, photograph in the thick fog for a while, and then be ready to photograph the brief transition period as it thinned, a time when brilliant and stunning but ephemeral light may appear. During my short drive to this location the fog remained thick, but just before reaching my destination it began to clear, likely because ground fog doesn’t stick around as long in the hills. As I parked and loaded up a light load (my lightweight trail photography setup) there were still some pockets of fog clinging to the hillsides, but in most places there was instead a sort of haze that glowed when I photographed in the direction of the sun. I’m very fond of this kind of light, so I quickly looked for subjects that I could use to advantage, and I soon found this tree standing on a grassy hillside and silhouetted against the glowing atmosphere beyond.

Geese, Tule Fog, Autumn Trees

Since it was December 1, it seemed like time to start my annual series of visits to California’s Great Central Valley to photograph migratory birds and the landscape of the place. (Actually, I had made one preliminary and very quick visit about a month earlier, but too early for the birds shown in this photograph.) There is a ritual about these visits which, for me, are typically one-day affairs that start very early and end rather late, with a fair amount of driving involved. Up well before dawn, I drive a couple of hours in darkness and often fog, arriving perhaps a half hour before dawn to the stirring sound of many thousands of birds, already awake at morning twilight. I photograph intensively for at least a few hours before taking, at last on most days, a midday break. By mid-afternoon I’m back at work again, photographing through the peak of the visual crescendo just before sunset and then continuing for perhaps another half hour or so until the light is gone. I pack, get into my vehicle, and retrace my two-hour drive back home. (At least the shorter daylight hours of this season allow me to get up a little bit “later” — if you consider 3:45 or 4:00 AM later — and return home in time for a late dinner.)

On this first day of December it was incredibly foggy when I arrived — so much so that it was really hard to make photographs. I usually enjoy photographing in the fog, but this was so thick that almost no sunrise light managed to color the gloom. But before long the light began to come through the fog and eventually I found a moderately large group of white geese settled in on a pond. Among them I saw Ross’s and snow geese, and beyond them there were trees with fall foliage.

I arrived at one of my favorite migratory bird locations before dawn. It was foggy, but the tule fog was already beginning to thin even as the first light came to the sky. Often when I arrive I hear nearby flocks as soon as I get out of my car, but on this morning the birds all seemed to be a bit further off in the distance. In fact, my initial inclination was to photograph landscape, since it didn’t seem like there were all that many birds around..

I went ahead and got ready to make some landscape photographs in the fog as dawn came closer — it seemed like one of those mornings when the fog was shallow enough that the colors of sunrise sky might suffuse the scene. But the fog was thick enough that it was difficult to find subjects to anchor the landscape… until a large flock of geese began to take to the sky just beyond a few scattered bushes and small trees. I quickly swung the camera in that direction and photographed as the flock rose into the colorful, foggy sky.
