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? :-)

Red-Wing Blackbirds, Twilight

March 28, 2018 G Dan Mitchell 1 Comment

A huge flock of red-wing blackbirds wheels in the twilight sky

First, a confession. Although I’m almost positive that the little black spots in this photograph are individual red-wing blackbirds, I was not actually close enough to verify. I had seen quite a few of those specific birds here earlier and none (or very few) of the birds that I might mistake for them, such as tricolor blackbirds. The rediwings are ubiquitous here in California and, I suspect, many other places. Before this past year I had mostly noticed them as individuals or in very small groups, often perched on a fence or tree or similar. I also sometimes saw them in groups of perhaps a few hundred.

This was the first year that I saw these small birds collect into extremely large group of many thousands of individuals. (In at least one case, I would estimate that there might have been multiple tens of thousands. On that day I saw then in the far distance through light fog in the very early morning — too far away to photography.) These really big groups sometimes perform remarkable group aerial maneuvers, with the entire flock spontaneously changing directions, ascending, descending and forming unusual patterns in the sky. In this photograph we see a diagonal boundary between the main group and a smaller group against twilight sky.

Building 259

Building 239, Mare Island Naval Ship Yard

In mid-March I returned to the old Mare Island Naval Ship Yard to do night photography with some of my nocturnal friends, a group of photographers with connections through Bay Area night photography guru Tim Baskerville who has been photographing, teaching, and generally promoting night photography for decades. We assembled well before dark, and as I arrived I kept my eyes out for structures on the old ship yard that might be interesting to photograph after sunset. About a half hour before the sun went down we began to head out to start out night’s work.

I planned to photograph around the “historic core” of the facility, but I decided first to drive back along my arrival route to where I had seen these buildings and few others that caught my attention. I started with a building that I have photographed in the past, and the sun set as I worked that scene. The soft, blue early twilight changed the appearance of the buildings, giving the foreground building 259 a blue cast and altering the color of the further building. I’m intrigued by these “round” buildings (what I grew up calling Quonset huts), and here I wanted to contrast its shape and color with the squared and pinkish background building.

Trees In Sun, Cliff In Shadow

Sun from behind an ice-rimmed granite monolith lights a row of trees at the edge of a meadow

I made this photograph on a day of somewhat ephemeral conditions. There had been snow the day before — light snow, but in very cold conditions. On this morning the storm had passed, but it was so cold that a thin layer of snow was still there. It was in the meadows, on the branches of trees, and collected on every small irregularity on the granite cliffs above Yosemite Valley. At the moment I made this photograph the sunlight, shining through thin clouds, had just arrived on the closest trees, while those in the distance remained in cold shadows.

The light and the snow patterns on the face of the granite monolith are remarkable. The small amount of snow — perhaps only and inch or two — brought the patterns of cracks and small ledges into relief, making visible features that we might overlook on a warmer day And the light on the cliff is rather blue since the face is illuminated not by direct sunlight, but instead by the giant “light panel in the sky,” which happens to be very blue!
