Sunset light on dissipating thunderstom clouds above granite slabs, Yosemite National Park.

Late on this September afternoon in the Yosemite back-country I had a good idea that something might happen around sunset, but I could not have known in advance just how intense the cloud color would turn out to be. The set-up was classic. Thunder storms had built up throughout the afternoon, and by late in the day I would see and hear large storms to my north and east – though I remained right on the edge of the storm potential as I was a bit further west. As evening approached the cloud-building forces began to diminish, leaving the tops of the larger cells unsupported, and they began to thin and stretch westward, curving up and over my location along the Tuolumne River.

Knowing that interesting light of one sort or another was probable, I walked to an area of granite slabs and bowls that I had photographed when visiting this area at the start of my trip nearly a week earlier. As I considered a few photographs of the granite and trees in that area, my attention kept being drawn to the sky. At first it remained a relatively low contrast mass of gray, though the thinning clouds started to allow views through falling virga towards more distant clouds that rose into the sunlight. Then, as the sun dropped and the foreground lost the direct light, the clouds began to light up and take on wildly saturated colors. (A technical note: in many of the photographs, though not in this one, the dynamic range between cloud highlights and foreground was so large that it required multiple exposures separated by up to five stops to capture it all!)

I moved to the base of the granite bowl in which I had photographed rocks and small trees a week before when I saw these spectacular clouds building to the north west. The color was simply unbelievable – and you can see that the intense saturated light was not just in the sky, but that it also colored the granite near the bottom of the image. For this photograph I used a short focal length to try to take in a large section of the flowing and wildly shaped and colored clouds.

A tree and granite slab are lit by brilliant sunset light from a dissipating evening thunderstorm, Yosemite National Park.

This was another of those sometimes-surprising bursts of evening Sierra color that results in effects so gaudy that they almost seem unreal – but this is real. I was camped down in a valley among trees so I wasn’t initially expecting much in the way of spectacular sunset photography. Instead, I planned to take advantage of the early shadows in the valley and get some evening photographs under soft light without any direct sun at all. I first worked some moving water where the nearby river flowed across granite slabs, and then I contemplated photographing some small plants in deeply cracked and patterned granite. As a worked my way across this granite, I remembered a small tree on the other side of the bowl that had looked like an interested photo subject a few days ago, so I walked over to that area where the tree stands in a shallow granite bowl.

Earlier in the afternoon I could see huge thunderheads building up to my east, but they did not move far enough west to affect me with anything more than a bit of gray sky. However, as the clouds built up to higher elevations, their tops began to take on the familiar “anvil” shape and the upper portions of the “anvils” began to spread to the west and out over my position. This is a classic setup for potentially spectacular evening sky color. Near sunset the clouds can pick up intense red/orange coloration from the sun setting in the west. At the same time, the storms begin to dissipate, creating semi-transparent “curtains” of virga (falling rain that doesn’t reach the ground), unusual shapes along the bottoms of the clouds, clouds emerging out of the gray murk as the sunset light picks them up.

As I arrived at my little tree, I quickly lost interest in that subject as the cloud light show began. First the bottom of the thunderhead began to turn brilliantly orange and red. Then the lower reaches of the small storm began to produce very unusual cloud shapes including mammatus clouds. Virga produced a brightly colored by semi-transparent scrim. It quickly became so bright that the red/orange colors began to wash the granite bowl, and I turned my camera from the little tree to the uphill granite surfaces and the clouds above.

In this vertical format image the tip of a small tree extends above the top of a dome-like area above me, and the brilliant light from the clouds washes the dome with color. The colors here have not been “amped up” in post – in fact, I’ve actually toned some of them down a bit!

Sunset Virga, Mount Conness

Sunset Virga, Mount Conness

Viewed from Fletcher Lake, virga illuminated by sunset light falls over the Sierra Nevada crest near Mount Conness – Yosemite National Park, California.

I’ve had this one sitting on my (computer) desktop for the past couple of weeks, so I think it is time to post it. On this late summer evening that in many ways felt more like early fall, a surprise thunderhead rose up above Mount Conness in the late afternoon, dropping rain for a while and continuing to drop virga as dusk came on. (“Virga” is the precipitation that falls from high clouds but evaporates before reaching the ground.)
