Detail view of a section of a Yosemite Valley granite cliff face

Yosemite, and especially Yosemite Valley, is famous for its “granite” (quotation marks for any geologists reading this post…) cliffs, towers, domes, slabs, and other formations. While we tend to think of this rock as being “gray,” the coloration varies quite a bit depending on the nature of the rock itself, the presence of lichens or plants, and on the light. Almost everywhere the expanses of granite are cut through by intrusions of different colored rocks. I don’t usually think of this particular face as being all that colorful, but on this morning the light somehow brought out the rust-colored tones on many sections of the rock.

I did just enough rock climbing many years ago to have developed memories of the sensations of such rock, from the cold and smooth slabs, to sharp edges of cracks, and rough surfaces (you hope!) on some friction routes. A close look at this section of cliff reveals an amazing variety of surfaces and irregularities. Perhaps most obvious is the large, curving vertical crack towards the left. The dark water stains are also striking, as is that rust colored rock. A closer look reveals other patterns, including a diagonal rising from left to right.

I made this photograph on a day of somewhat ephemeral conditions. There had been snow the day before — light snow, but in very cold conditions. On this morning the storm had passed, but it was so cold that a thin layer of snow was still there. It was in the meadows, on the branches of trees, and collected on every small irregularity on the granite cliffs above Yosemite Valley. At the moment I made this photograph the sunlight, shining through thin clouds, had just arrived on the closest trees, while those in the distance remained in cold shadows.

The light and the snow patterns on the face of the granite monolith are remarkable. The small amount of snow — perhaps only and inch or two — brought the patterns of cracks and small ledges into relief, making visible features that we might overlook on a warmer day And the light on the cliff is rather blue since the face is illuminated not by direct sunlight, but instead by the giant “light panel in the sky,” which happens to be very blue!

The little bit of sunlit granite cliff on the right side of this photograph has long intrigued me. When the light hits it a highlight is added to a scene that is often otherwise almost completely in shadow. The light only happens for a short period, since the sun has to rise above the thousands-of-feet-high cliff above and then find its way down at just the right angle. Basically, it is only going to happen in the morning at this time of year, and for a short time at that. On this day I photographed it just after new snow had fallen the night before, coating trees and granite with a thin layer of snow.

The color of this scene is perhaps also worth mentioning. I decided to “go with the blue” on this image. Deeply shaded areas that are illuminated by open sky are often far bluer than we might think, something that photographers soon learn to recognize. When we look at such a scene with our eyes and our brains visual processing system, our brain tells us that, for example, the snow in this scene is white. But objectively speaking it is very much NOT white — it is the blue of the sky. In many cases photographers — including me — will adjust the color of the blue shadows in post to make them a bit closer to how we recall the scene, but another option is to leave it just as blue as it actually is… which is what I’ve done here.

During this weeklong late-February visit to Yosemite National Park (thanks to an artist-in-residency from Yosemite Renaissance) the weather was quite cold, even for the Sierra Nevada in winter, and there was light snow at times throughout the period. In many ways, this is almost idea for photography in Yosemite Valley — although the snow and cold complicate the process of making photographs, they also have some beneficial effects. Obviously, the snow changes the appearance of the landscape in many ways, and the cold weather tends to reduce the number of people who are out and about.

It had snowed a few inches in the Valley since the previous afternoon. (The storm was varied, and I work up to considerably more snow than that where I was staying, outside the Valley.) Because of the unusual cold — it barely got out of the teens — the snow stayed “dry” and didn’t immediately melt out of the trees. In the photograph you can see a bit of snow in the meadow on the Valley floor, but there was more up higher, and the trees ascending the further slope all were fringed with it.
