Many times when I have photographed in red rock country I find myself looking for other subjects that work with the sandstone to produce compositions — juxtapositions of features, trees, a bit of sky or clouds, water, light and shadow, and all of the other things that are part of the experience of this Southern Utah landscape. But at times it strikes me that the rock itself can be the entire subject. This is one of those photographs.

These masses of sandstone are remarkable on their own. They may first seem somewhat undifferentiated, but a closer look in the right light — in my view, the shaded light in canyons is ideal — reveals remarkable variations and detail. The color of the rock varies greatly depending upon time of day and, especially, the color of reflected light bouncing between anyone walls. Cracks and imperfections mark the rock even on the smoothest sections. And an infinite variety of markings combine on the surface — internal irregularities, color differences where the surface has been disturbed, and everywhere vertical lines formed by seeping and flowing water.

There are so many things bound up in photographs like this one that it would be possible to write a book about it. This was my first visit to this landscape and, as such, it was part of the rare experience of being in a place that I did not know at all. It also raises questions about the value of photographing icons — hint: there is some, but it is complicated. It is a photograph I made some years ago, bringing up the value of revisiting photographs that were originally left behind or perhaps interpreted differently. It brings up the questions about what landscape photographers do when the landscape is inaccessible.

I made the photograph during perhaps my first hour or two in Arches National Park. For someone who read Abbey’s “Desert Solitaire” decades ago, this visit was a long time coming. And, aside from that book, I came with few preconceptions about the park, and I had not researched before arriving. Consequently, as we drove in late the first afternoon I had almost no idea of what I would see. I was amazed.

Tufa Field, Dawn

One of the great privileges about photographing landscapes is that I get to wake up way before dawn so that I can be in place before the sun rises. No, really. Like many of you, I used to dread the idea of getting up in the dark, and I could not fathom how anyone could actually want to do this. But even though I’ll admit that the sound of an alarm at, say, 3:30AM is not something I look forward to, at least I now understand that there are rewards that make it worthwhile. Such as standing alone in an immense, silent space as the first light creeps over mountains to the east.

Tufa, from I’ve come to understand, comes in quite a variety of shapes and sizes. There some well-known tufa structures that have been photographed lots of times not far from here, and I’ve photographed those, too. I have gotten to know some absolutely huge tufa formations in desert areas around Death Valley. (If you were familiar with only the first one I mentioned above, you might not even recognize the second as an example of the same thing.)These very small tufa structures embody yet another form of this stuff.

Marbled Canyon Wall

Marbled stone in a Death Valley canyon wall.

This little section of canyon wall is one that I’ve marveled (marbled?) at for years, stopping there every time I visit this canyon and pondering how to photograph it. Although I find the patterns (and what they imply about the geology of this place) to be remarkable, it isn’t each to find a way to photograph them the way I want. On this visit the canyon was quite dark and the light filtering down from above was soft and blue-toned.

I am about as far from being a trained geologist as one can be. I have never taken a single course in the subject, though I have read a bit. Nonetheless, I always marvel at the record of time and geological forces that created a little spot like this. Some material was, I presume, laid down “here” over a long period of time. Additional time allowed for it to transform into rock. As geological forces on various scales did their work, cracks appeared that permitted the entrance of entirely different material to create what we see as veins — but which are perhaps better thought of as layers. Eventually the force of water (and perhaps a weakness in the structure of the rock?) exposed this rock to the light. And then I arrived to photograph it…
