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.

When photographing dunes that are new to me, I have little to go on when I first venture into them. I typically have to 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 that 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 had 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.

Desert Mountains, Before Sunrise

One thing that has always appealed to me about the desert landscape — which for me often means the Death Valley landscape — is that the geology is laid bare almost everywhere. So many landscapes are to a great extent about what covers them — the forests, grasslands, lakes, meadows, rivers, and more. But here most of the vegetation is so sparse (or it matches the colors of rocks and soil so well) that we see straight to the underlying earth — the canyons, the colors of rock and soil, strata twisted and uplifted, runoff channels, landslides, fans, and more.

This canyon descends toward Death Valley from high in the Panamint Mountains, following a twisting path down from the heights as it links up tributary valleys and eventually forms a broad wash that spills out at the top of a gigantic gravel fan. I made this photograph before sunrise, when the soft, early light suffused the canyons and revealed subtle details that can be lost in harsher light later in the day.

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.
