Morning sun back-lights the dense pattern of folds in a small gully at Zabriskie Point, Death Valley National Park, California.

In some ways I think this is one of the more subtle and complex of the various photographs I have made that isolate small sections of the Zabriskie Point landscape, especially the eroded patterns of the small gullies below the main viewing area. This photograph, like many in this series, was made after the normal “dawn light” time period, and at this time the sun is higher in the sky. It begins to back-light the tops of the furrows and gullies and the brighter light reflects down into the lower portions of the gully. There are a tremendous number of overlapping ridges and the color variations are quite large, though subtle at the same time. Some areas have a very blue cast, being in shadow and lit almost completely by the open blue sky. Others take on warmer tones, especially if they are illuminated by light reflected from the warm-tones earth. An area of thin clouds was floating above the scene and its shadow slightly softened and muted the light that otherwise might have been quite stark.

Patterns in eroded shoreline sandstone rocks at the Point Lobos State Reserve, California.

The rugged Point Lobos shoreline in places exposes some very interesting rocks, including sections like this one where layers of different colored sand stone are gradually worn away, revealing underlying layers of different colors and textures and sometimes exposing surprising color contrasts. On days when the light is very soft (or very boring!) I may seek out some of these rocks and photograph them since the softer light lets details appear that might easily be washed out in harsher light.

Dead Branch, Glaciated Granite

A dead branch lies on glacially-polished granite in the Yosemite National Park back-country.

I made a promise to someone to not say where this photograph was made – I’ll just say it is in Yosemite National Park. But the exact location really doesn’t matter too much, as these large expanses of glaciated granite slab are a common feature throughout the park, and you could find similarly interesting geology in thousands of locations.

I was a little surprised to find this weathered branch in this location, since it was a good distance from any trees and also not near any flowing water. Besides its location, a few other things about it caught my attention. First, its curving shapes lined up in a way tht seems to tie in with the bit of glacially-polished granite that lies beneath it. (And, yes, this is exactly where the branch was when I found it.) In a way, the larger shape of the lighter area of granite winding across the photograph from side to side almost seems like a much thicker echo of the curving shape of the branch. In addition, the warm brown tones of the branch seem to stand out a bit – though perhaps more in a larger print – against the relatively drab color of the rock.

Natural Bridge Canyon

A gravel wash in the bottom of the narrow confines of Natural Bridge Canyon, Death Valley National Park.

These narrow canyons, of which there are a number of great examples in Death Valley, can provide some interesting photographic opportunities, but they also can pose some real challenges. Much of the rock in these places is, frankly, rather drab and of low contrast. However, at the right time of day and on a day with the right light and in the right parts of these canyons, the glowing light reflected down into the canyons from overhead rock walls can produce warm and diffused light and bring interesting colors to the place.

I made an unusual decision to use a very long focal length for this photograph – it was shot with a 100-400mm zoom at 330 mm. More typically I would probably tend to use wide angle focal lengths in the confines of such a canyon. However, because I wanted to juxtapose the different colors and shapes of the sections of canyon wall along the narrow and twisting wash, I chose the long lens to compress the distance. Although I think the photograph creates a feeling that I’m positioned very close to the foreground rocks and the darker bit of canyon wall on the left, I was actually quite a distance back from this spot.
