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…

Deep in a desert canyon, a dormant plant waits for moisture.

This plant grows in a very unlikely place — in a small crack in the rock face of a canyon wall in a deep wash where there is usually no water at all. No doubt it produced this now-dormant lush growth during a brief wet period when, like so many desert plants, it took advantage of a short interval when moisture was relatively abundant. And now, somewhere under all of these dried up branches and leaves, the heart of the plant waits for the next rain.

By the way, I don’t mind at all if you want to look for analogies to the current societal conditions of social distancing, of putting life on hold, of managing to exist in a dark place, waiting for better conditions to return. Feel free!

An anomalous white rock rests against dark rock deep in a Death Valley canyon.

Desert canyons, especially in an arid place like Death Valley, are refuges from the harsh environment. Not that they are entirely gentle and friendly places, being periodically scoured out by floods and left covered in rocks. But they offer shade, sometimes sources of moisture, and occasional plants. The deepest and narrowest are quiet and still places.

They are transitory landscapes, on time scales that range from annual to much longer. Cut through by flowing water and weaknesses in the rock, they reveal strata from long ago. That flowing water inexorably moves material down from the peaks toward the playa, and almost anything we come across in such canyons will only be there temporarily. I don’t know enough geology to offer too many facts about this rock, but its light color against the surrounding dark rock was striking, as was its upright position.

Early Aspen Color

Early autumn season aspens begin to change color.

As fall approaches I always anticipate the color change of aspen trees way in advance of the actual event, and I start watching for early signs more than a month before the color peaks. Way back in August I typically find a few early clues — yellowing corn lilies, drying meadows — and at some point in September I find my first few yellow aspen leaves. The change begins in earnest by the first week of October, and that is when I made this photograph. At this point, the aspen trees seem to move toward a sort of “lime green” color, often with a few interspersed yellow leaves, and in the right light you can convince yourself the fall colors have arrived.

There is a useful lesson about lighting in this photograph, too. Although this scene seems pretty straightforward, there’s more going on with the direction and color of the light than you might first notice. This grove of trees is, indeed, in the shade. The camera is pointing roughly east, a tall ridge rises behind this little grove, and it was still shading the trees hours after sunrise. This provides soft light that fills in shadow details much better than direct sunlight. Look deeper into the grove and beyond and you may notice that the color becomes more blue. Light in shadows is usually quite blue — after all, the main light source is the very blue sky! But the trees in the foreground are not very blue… and there’s a reason. Behind my camera position (if we could turn around and look backwards) was a very large mountain in direct sunlight, and the reflection of that light was strongly diffused and directed straight into the grove, warming the colors and highlighting the front trees.
