Overlapping ridges of red strata in the Utah backcountry.

Our plans for this day in Southwest Utah were a bit vague. Initially I had in mind perhaps three or four possible destinations, but recent rainfall (which leads to mud, with its pluses and minuses) convinced me that perhaps a drive on a long, isolated backroad might make more sense than a foray into a deep and narrow canyon. Besides, I knew of at least one canyon along the route that was less likely to be muddy, being a bit wider and shallower. So off we went.

One thing about a couple of photographers driving through a fascinating, beautiful place is that… there are a lot of stops. By the time we got to a decent turn-around point on this drive we realized that it was late enough in the day that we probably wouldn’t have a lot of time to explore on foot on the way back. I made a guess that a particular section of narrow canyon might be easily accessible from our route, though I couldn’t be sure since I had not previously visited that canyon. We stopped, walked a bit, and quickly realized that the entry was a bit more complex than we had in mind. We tried another canyon entrance with similar results — given more time we could have gone in, but time was the one thing we didn’t have. But along the route on the way in I had noticed this impressive are of impressively red and impressively eroded strata, and we had time to stop and photograph it before heading on.

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.
