Overhanging Canyon Narrows

Image March 3, 2025 G Dan Mitchell Leave a comment

I make (at least) one annual photography trip to Death Valley National Park, and I’ve been doing so for something like two decades. My favorite time to visit is in the winter. This year’s trip was during the final days of February — the calendar said winter but a heat wave made it feel more like summer, with temperatures up to ninety degrees. Many areas of the park were inaccessible due to washed out roads and to construction, so I visited a few familiar places and went to a couple of new ones.

This slot canyon is an old favorite, and I have hiked and photographed it several times in the past. The “slots” are great destination on days, like this one, when it is both windy and hot. Death Valley slot canyons are different than the better-known Utah-style slots. They often feature rather dark rock, and the slots are often shorter. In this canyon there are several sections of these narrow passages, but in between there are longer sections of open canyon.

Patterned Cliff Face, Detail

A small section of shaded Sierra Nevada cliff reveals remarkable details of dikes, fractures, color, and stains

Most often when I think of large rocky faces in the Sierra Nevada, the clean, smooth, and almost uniform faces of Yosemite granite come to mind — large expanses of nearly unbroken rock shaped by glaciers. However, when I get into the high country and the other areas of the range I am reminded that things aren’t quite so simple. In places you can find mountains cut through by giant dikes of non-granite rock, or you might encounter the remnants of more ancient layers that lay above the granite intrusions and today give us red, black and other colors of material.

Since I’m no geologist, I can’t explain the details of the face in this photograph, but I can share a few observations. It is the headwall of a high bowl that contains a subalpine lake, and the area does show signs of glaciation. The fact is gigantic, and this is just a small section. It is far from uniform, with mostly gray rock cut through by thick intrusions of lighter material, and the whole thing cracked and fractured. In many places the surface has been deeply stained as water has flowed or seeped across it.

Patterns In Granite

Patterns in a section of Yosemite Valley granite

Of all the things that characterize and define Yosemite, rock may be the most important. The Valley itself is lined with huge granite* forms in the shapes of domes and cliffs and more, carved by water, glaciers, and slow erosion. Wandering about the Valley one eventually becomes aware that the granite “moves,” and that giant chunks have fallen from the surrounding heights and sometimes managed to travel a good distance into the valley — a sobering thought. This rock continues into the high country, where some of the same features are found, along with others — the glacial “erratics” left behind as ice retreated, places were rivers flow across smooth rock, meadows dotted with boulders.

The character of granite on the large scale is hard to miss, but its character close up is also fascinating. Many years ago, for a few years, I was a bit of a rock climber. As a climber one gets “up close and intimate” with rock, learning (and remembering the tactile qualities) of the rock — smooth, straight cracks, rough, covered by lichen, disintegrating, marked by water, and more. That may explain why this little spot caught my attention. Quite a few stories are in this rock. It lies at the base of some very large cliffs, suggesting its source. It is covered by lichen, part of the reason for the color variations. Stained streaks produce vertical lines, and one odd section, which must be harder than the rest, angles up from left to right.

A geologist friend has pointed out to me in the past that “granite” is not a technically correct blanket description for the rock of Yosemite. I’m using the term in the casual and familiar sense. And for those who get this far, did you notice a compositional link to the recent redwing blackbird photograph? :-)

Burned Forest, Yosemite Valley, Autumn

May 24, 2011 G Dan Mitchell 2 Comments

Evening light in a burned section of the forest on the floor of Yosemite Valley.

I’ve been sitting on this photograph for a while, so I figure I’ll post it now. I made it last fall – on Halloween, actually! – during a fall color trip to the Valley. Late on my final evening I finally stopped and walked out across the old terminal moraine that crosses the lower Valley not far upstream from Pohono Bridge. (When you drive into the Valley, the road splits, and before long you’ll see the south end of this feature to your left as you go up a short climb.) I started at the north end and as I walked south looking for a photograph it was a very quite, still, and cold evening.

I finally found a spot where I could go down the lower side of the hill just a bit and find a relatively clear shot through the trees that wasn’t blocked by foliage closer to my position. This area has been burned, and I assume that it is the result of one of the management burns that often occur late in the season. These fires attempt to strengthen the forest by reintroducing the natural process and cycles of fire. The result is interesting charring patterns along the lower portions of the trees, temporary burned undergrowth, and then as the recovery takes place a much more open and airy sort of forest as you see in this photograph.
