Angle of Repose

Angle of Repose
Sand dune patterns, Death Valley National Park.

This “intimate landscape” is a sand dune vignette made in a specific place but which could be found almost anywhere. A close look may reveal some details that desert and sand aficionados may find interesting. The large patterns are typically found on one side of dunes where sand blown over the top of the dune collects below. The smaller “ripples” are a common feature of dunes, too, and these are completely undisturbed since the dunes are somewhat remote. Looking even closer may reveal some tinier patterns and tracks across the face of the sand.

The term “angle of repose” refers to the steepest angle at which a material, such as this sand, might collect without collapsing or sliding downhill. It is also the title of a wonderful Wallace Stegner novel, and that is where I first encountered the term. Fans of the history of the American West, especially the part that came after initial explorations, and especially those who have roots in the west may enjoy the novel as much as I did, with its connections to places and types of people that I know from my own experience.

Layers, Sunset Dunes

Layers, Sunset Dunes
“Layers, Sunset Dunes” — layers of desert sand dune formations in the last sunset light of the day.

When photographing dunes that are new to me, I have little to go on when I first venture into them. I typically start walking toward them when the light is still somewhat flat and harsh, or before dawn when it is dark. It is difficult to imagine the details of how the light will evolve. I make some guesses based on the direction of the sun, how I think distant ridges may affect the arrival of shadows, and what I can see of the dunes’ features in the less-than-ideal light. In the end, I’m almost always surprised by how these first visits play out.

I approached these dunes in the late afternoon in preparation for sunset and evening light. I picked out a destination along the base of a particular dune where I saw some potentially interesting plants. Because the ridges to the west are quite low here, I guessed that I’d have a bit longer period of colorful light and longer shadows later on. Initially I walked past the location of this photograph because the textures of the successive ridges had little contrast in the daytime light. Later, as I finished photographing other nearby features that fell into shadow, I happened to look back in this direction, where the very last bit of colorful light was now delineating these shapes as evening shadows approached.

I photographed this scene on my first visit to this location. Going to a new location for the first time can be a complex experience. There is, of course, the excitement of photographing something new. But there are other feelings, too — uncertainty about where to start, a bit of confusion and guesswork about how the light will evolve and about where to find the most interesting subjects. While sometimes the new simply seems exciting, other times it is almost overwhelming. For the most part I think I’ve learned to go with the flow, knowing that I’m going to make some wrong choices, that I’m acquiring knowledge that I can use when I come back, and that most likely I will at least come away with something interesting.

Approaching this spot, at first I wasn’t quite sure where to begin. I had an idea of how the light might evolve as the day ended, but when I arrived the light was less than spectacular. Another thing I have learned is that it is often better to just start making photographs rather than waiting for the perfect to reveal itself. Setting up, looking, and making exposures often primes the pump, and soon I start to see things more clearly. It is also good to be flexible and ready to be surprised. This photograph is built around one of those surprises. At first these patterns of windblown sand seemed uninteresting and I went on to photograph something else. But in the very last direct sun (you can see the edge of approaching shadows at lower left) the low light revealed shadows and textures that had been hidden earlier, and the color of the light became momentarily intense.

You may have noticed that few of my photographs from Death Valley feature the usual iconic subjects. Perhaps an explanation is in order. There’s nothing at all wrong with photographing those famous subjects — as someone once said, “There’s a reason they are icons!” I photograph them, too, when the conditions are special or unusual. In the right conditions you might even find me lined up at Zabriskie Point at dawn! (Though these days, if I photograph that subject, it is more likely to be in the middle of the day or perhaps at night. That’s a long story — too long for this short post.)

These days much of my photography in the park falls into a few basic categories. There are some photographs that I have had in mind for a long time that still haven’t quite come together the way I want, and I return to these subjects regularly and continue to work on them. I’m also very interested in pushing out the boundaries of my relationship to this landscape, and on every visit I got to places that I have not visited before. Another approach that has come to interest me more and more here is to excerpt small bits of the larger landscape and treat them as the subject. (I believe that sometimes a close look at a fragment of the landscape can tell us more about it than a photograph that tries to “include it all.”) This photograph falls into the latter category — this little ravine is high on a hill in a place where, I’d wager, most people probably don’t even notice it. But at the right moment in the right light it becomes something special.
