Varied sand patterns on a fold in dunes at Death Valley National Park.

One of the myths about sand dunes is that their features are in motion, being blown across the landscape by winds. The fact that so many features — ripples, waves — remind us of water reinforces the illusion. But here the fluidity is of a largely static sort, and these features tend to remain in much the same place over long periods of time.

The reasons that dunes come into existence begin to be obvious when ou get to know them. They tend to be in windy places where natural features obstruct, divert, and slow the winds, causing them to drop their load of airborne dust and sand. While these broad features are easy to understand, I remain mystified by the smaller scale features like those seen in this “intimate landscape” photograph — the waves, ridges, valleys, drop-offs that also tend to remain fixed.

Desert terrain of contorted and folded strata

It has been well over a year since I made this photograph, but I remember the evening well. I had arrived in Death Valley earlier in the day, by way of a detour through the Los Angeles area, found a place to camp, and was now starting several days of intensive photography in the area. In the evening I headed south in the park to a particular knoll that I have photographed from before, with the idea of photographing a particular subject in some light that I had in mind.

I found and photographed that subject, though conditions weren’t quite what I expected. A combination of evening haze and strong winds presented some challenges — and I’ll need to return to the spot to make that photograph that I originally envisioned. However, from this elevated position there was a spectacular view of arid and rugged desert terrain in the opposite direction, so as the light on my original subject faded I turned my attention in this direction. There are many things to think about and say about terrain like this, but I’ll mention one thing. When we look at such a place our first impression is of the rugged dryness. But when we look again we see evidence of water everywhere in such a landscape — in those valleys, and in the gullies tracing twisting lines down the faces of the formations.

Waterpocket Fold Terrain

Deep erosion gullies below an uplifted rock band empty into the valley below, with rugged terrain extending into the distance

Until a few years ago, although I had heard the term “waterpocket fold” before, I was almost completely unaware of what this geological feature is. Since that time I have visited it several times. On the first occasion I visited the area, but I still did not understand the geology. I “got it” that there was some sort of uplift — the land rising to the west of Capitol Reef was a pretty good clue — but I did not understand or really see any of the connections. I recall stopping at one road side pullout and seeing a sign about it, registering that it is something important, but not really understanding.

On more recent visits the reality of this huge and striking feature has finally sunk in. I began to see it a few years ago on a trip that took we away from main roads and way up on a rocky ridge from which I could look down into the eastern valley and clearly see some of the larger patterns — sinuous lines of angled rock, the valley twisting gently into the distance in the south. On the most recent visit it began to make a lot more sense, as I noticed features like the shadowed cliff band across the center of this photograph, which more or less represents the remaining underside of a layer that long ago continued on up into what today would be the sky. Its edge overhangs the softer material below, though it still erodes into the bottom of the valley. Further to the east in this photograph the impossibly rugged terrain of arid strata continues, eventually rising to a mountain range in the far distance.

This landscape could hardly be more different from the landscape in yesterday’s photograph. The earlier photograph was of Drake’s Estero, at the Point Reyes National Seashore, made on a day that was almost entirely foggy until a brief interval of filtered sun illuminated the blue waters of the estuary, a bit of green on a peninsula, and distant sky and water. None of those things are found in this photograph.

This landscape from Capitol Reef National Park is austere, arid, and quite rugged. It has a special beauty, but it is not a beauty with soft edges, misty skies, and water. Here the land is laid bare, seeming from a distance to be devoid of plant life. (Once inside this landscape, it turns out to be a bit more alive than it might seem.) Geology and the effects of time are visible in these places with their colored layers of rock, deeply cut valleys, and rugged erosion forms. Here gullies lie below rocky ridges, and two valleys come together in a flat area laced by stream beds.
