Remarkable things happen to the light deep down in the recesses of narrow sandstone canyons. The light is rarely direct, more often bouncing many times among red canyon walls. As it does, it softens, diffuses, and picks up the colors of the red rock. At the same time this landscape is open to a band of blue sky — what I think of as a giant blue light panel — and this color becomes part of the mix, though this light can follow a more direct path and fill in shadows. When you stop to consider what it really looks like, it almost seems unreal.

We were deep in such a canyon, spending a day heading deeper and deeper into it as it cut into the landscape. By the point at which I made this photograph, that band of blue sky was increasingly narrow and we encountered less and less direct sunlight.

While I often refer to this part of the world as “red rock country,” in truth the rock is rarely actually red, and its coloration changes radically depending on when and where you see it. In deep canyons it can become, in objective terms, almost purple. At sunset or sunrise it edges far into the warm portion of the spectrum, varying on gold, orange, or yellow. In flat light the intensity of the color diminishes. In some places colors on the surface of the rock are striking — either from material that coats it or the variations between old and new sections.

As I work on photographs I often have several open on my computer at once, with some of them staring back at me for weeks as I put off final decisions about how to interpret them. Recently there have been mostly photographs of this red rock country, and looking at those together has reinforced just how varied these colors are. This section of a cliff face at Arches National Park was photographed in very early morning light that shone at a low angle almost directly onto the the rock, and this light reveals details of the face that might not otherwise be seen with such clarity.

These canyons are simply full of fascinating details. Unlike much of my familiar Sierra Nevada landscape, where vistas can often go on for many miles, here the size of your world is much smaller. It is constricted to the width of the canyon, the distance to the upper rims (plus some sky), and upstream and downstream to only the next bends. So you are almost forced to focus on smaller details, of which there are many.

Here my attention was drawn to the rocks. I’m no geologist, and I only know enough to speculate about these things. But a close look at the rocks in this scene show material that was created in layers. Near the upper right corner, if you look closely, you can spot a place where there is a striking convergence of angles in the strata. And although this material was laid down in horizontal layers, over time it has been pushed and stretched and lifted until the formerly horizontal now angles up distinctly to the left. There is also an interesting almost vertical fracture between the more solid (and darker) rock on the right, and the lighter color of the broken rocks stacked up on the left.

I photographed this somewhere in Utah, almost certainly in Grand Staircase-Escalante National Monument, and I’m pretty sure I remember which little canyon I was walking through… but I can’t say that I recall the exact spot. We had driven to a rather out-of-the-way location, wandered up a shallow stream, and entered a lovely, quiet, light-filled canyon full of the usual twists and turns.

The canyon presented a veritable feast of photography — plants, reflections of sky and canyon walls in the water, sand, red rock walls, and more. Given the narrowness of the canyon, the subjects all belonged to the “intimate landscape” genre, and it was rare to have a view of anything more than a few yards away. And everywhere the star of the show was there light reflected down from above and bouncing off the sandstone canyon walls.
