These rocks tell a story, a profound one no doubt, but also one that this non-geologist is incapable of fully comprehending. But I do know a few things, and with that bit of knowledge and the time to observe, I can report that there is a lot to think about in places like this and, for that matter, the entirety of Death Valley National Park. A difference between this landscape and most others with which I’m familiar is that here it is almost entirely exposed rather than being hidden underneath forests and snow.

As I understand it, the course of many of the rocks here is sedimentary — they were formed under ancient seas. (Portions of the valley were submerged much more recently, and that shorter tale is visible, too, in places.) Those sediments sometimes captured creatures that became fossilized, as we see in the black spots in the rocks of this photograph. Then various geological forces lifted, tilted, fractured, and contorted these layers over a vast span of time. In many places in the park the strata are inclined upward as they progress to the west. Here one of the inclined rock bands contains colors that are the exception rather than the rule in this national park.

This is another photograph from my time exploring canyons on my recent Death Valley visit. The pandemic shutdown period — even though things were beginning to let up a bit — seemed like a good time to visit areas in the park that are less accessible and where I was more likely to find myself in splendid solitude. A barely saw anyone during my visit to this area, and I was the only person there when I stayed overnight.

Canyons have wildly diverse “personalities” and, like some humans, those personalities are subject to change. This canyon, like some others in this park, alternates between open sections with shallow-angle canyon “walls” and more constricted “narrows.” I made this photograph near the entrance to one of the narrows. At this time of day there was quite a bit of light filtering down from far above, bouncing back and forth between the eroded canyon walls and filling the scene with soft light.

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.
