Falling virga drifts below sunset clouds of an incoming late-autumn Pacific storm front

First off, the word “virga” refers to streaks or columns of precipitation that fall from clouds but do not make it to the ground. Virga can often create beautiful, delicate, and gossamer atmospheric effects, especially when the light is just right. In this case the condition was back and top-lit by low sunset light flowing upwards toward the base of high clouds from an incoming winter Pacific storm front.

This evening was (yet another) of those on which earlier unpromising conditions exploded with color right at the end of the day. We had spent the morning photographing birds (mostly geese) at a Central Valley wildlife refuge, taken a short lunch break, and then returned to the refuge for late afternoon and evening photography. The geese were wonderful and we made a lot of photographs, but it seemed like the light was going to “die” before sunset as those high clouds began to drift in from the west. That’s OK, as there are ways to photograph in that more subdue light, but I think we may have been mildly disappointed that the clouds appeared to preclude special sunset colors. So we went about our business of photographing birds, not thinking too much about the sky. Speaking for myself, though, at some point I began to notice a bit of color in the clouds behind the birds. I stopped for a moment and looked to the east (where the sunset colors first are seen before the sweep across the sky toward the setting sun) and noticed that some color was developing. In short order, the underside of the clouds began to light up, and right at sunset we were treated to an absolutely brilliant display of intense color to the west. Since I was shooting with a long telephoto I decided to try a few detail shots of small sections of the sky. If you look very carefully, you might be able to spot a jetliner heading into the sunset.

I made this photograph on a very cold early October morning high in the eastern Sierra after a series of early season snow storms had passed over the Sierra. The gravel road to North Lake had apparently just opened again on the morning I arrived, and few other people were there. I was there to photograph autumn aspen color, but the opportunity to photograph snow scenes so early in the season distracted me.

As I walked the road skirting the edge of North Lake, I passed by meadows that were completely covered by new, untouched snow. Here and there a few small plants managed to poke up from beneath the white blanket.

Merry Christmas and Happy New Year!

Dust Storm, Death Valley

A building dust storm begins to obscure the sky above Death Valley, California.

In retrospect, there were hints that this tremendous dust storm was coming prior to its actual arrival. Very early in the morning I had been photographing at another location and the light and atmosphere were a bit unusual. The dawn and very early morning light was beautifully warm, but the distant peaks were slightly obscured by a sort of atmospheric haze that is hard to describe but which I now recognize as being associated with incoming dust storms. Soon, large and impressive clouds began to appear high in the deep blue sky, but at about the same time the air closer to the bottom of Death Valley started to look increasingly opaque.

I left my early morning shooting location and began my trip home from Death Valley. After a stop at Furnace Creek – to treat myself to a real breakfast after days of camping – I headed north towards Stovepipe Wells. As I headed north I began to see the obvious clouds of blowing dust accumulating along the Grapevine Mountains, and shortly before the turn to Stovepipe I encountered the boundary between the relatively clear air and the murk of the dust storm that was growing directly ahead and off to my left.

Before entering the cloud – I had not choice since my route went that direction – I pulled over within perhaps a quarter-mile of the edge of the storm. Not wanting to risk dust getting into my camera, I unpacked my gear inside the car and decided to just use the lens that was already fitted to the camera. I stepped outside to find that lines of wind-blown dust were already streaming along the ground and that the atmosphere had taken on the strange and electric feel of these storms. Off to my left, the dust was beginning to kick up among some low, dark hills across a nearby wash, while a gap in the dust clouds momentarily left open a window to the bright sky and high clouds above.

Morning Squall, South Tufa

Morning Squall, South Tufa. Mono Lake, California. July 25, 2010. © Copyright 2010 G Dan Mitchell – all rights reserved.

The shoreline of Mono Lake as a morning squall drops rain over the Sierra Crest near Lee Vining, California.

This photograph is, in a number of ways, a sort of happy accident. I had been camped in the Tuolumne Meadows area for several days, doing photography in that area of the Yosemite National Park Sierra Nevada high country. On the previous day I had been caught out on a hike in a surprise thunderstorm without rain gear, so I was very conscious of the weather. That evening it occurred to me that given the approach of some monsoonal moisture and the already wet weather, that it was possible that interesting clouds might form in the Mono Lake area the next morning. (Mono at dawn is a spectacular place, but since I’ve photographed there quite a few times I don’t necessarily shoot there at dawn every time I’m in the area unless there is a chance of special conditions.)

That night I peered out of my tent from time to time to see if any clouds were interrupting the light of the full moon, thinking that this might be enough to get me to change my plans for morning photography and make the drive to Mono Lake. At one point a few clouds did dim the moon light, and a bit later a few showers came through. At this point I was pretty certain that the cloud potential would be there in the morning so I decided to get up a bit earlier and drive to South Tufa.

I thought I was up early enough. However, as I drove down highway 395 south of Lee Vining I realized that I had miscalculated and that the sun was already hitting the clouds! I experienced the photographer’s conundrum – shoot what I see here now, or race on hoping to shoot the planned thing. I decided to stop and shoot the very first light on the Sierra crest from 395 before heading on, but now my original plan for a pre-dawn visit to Mono was out the window. Soon I headed on down the road, turned off onto eastbound 120 and made my way to South Tufa just as the first sun was striking the lake shore. I quickly made it out to the tufa area and saw (how could anyone miss it!?) this giant cloud cell blowing up over the Sierra crest just north of Lee Vining.
