Detail, Granite Face

Detail view of a section of a Yosemite Valley granite cliff face

Yosemite, and especially Yosemite Valley, is famous for its “granite” (quotation marks for any geologists reading this post…) cliffs, towers, domes, slabs, and other formations. While we tend to think of this rock as being “gray,” the coloration varies quite a bit depending on the nature of the rock itself, the presence of lichens or plants, and on the light. Almost everywhere the expanses of granite are cut through by intrusions of different colored rocks. I don’t usually think of this particular face as being all that colorful, but on this morning the light somehow brought out the rust-colored tones on many sections of the rock.

I did just enough rock climbing many years ago to have developed memories of the sensations of such rock, from the cold and smooth slabs, to sharp edges of cracks, and rough surfaces (you hope!) on some friction routes. A close look at this section of cliff reveals an amazing variety of surfaces and irregularities. Perhaps most obvious is the large, curving vertical crack towards the left. The dark water stains are also striking, as is that rust colored rock. A closer look reveals other patterns, including a diagonal rising from left to right.

Fractured Granite

A fractured granite cliff in the Eastern Sierra Nevada

I made this photograph on a morning when I was in the eastern Sierra to photograph autumn subject, particularly the annual color change of the aspen trees. Being in a place where I have photographed many times, I quickly dispensed with the familiar (and even iconic) subjects in the area and then, as I like to do, simply wandered slowly with my eyes open, looking for little elements of the larger landscape that caught my eye. Although I have walked past this granite quite a few times, it may be the first time I have photographed it.

Granite (along with, as geologist friends might remind me, rocks informally referred to as granite) is ubiquitous in the Sierra, and is one of the most characteristic features of the Sierra Nevada experience. Not only is there a lot of it, but it has been laid bare by (mostly) glacial action, and it appears in its original locations and in places where the rocks have been moved by water and ice. As a person who has hiked here for decades and who spent a few years as a rock climber, I developed an intimate familiarity with this rock. It can be smooth or rough, uniform in color and texture or interspersed with veins and crystals. It can be freezing cold in winter or benignly warm on a summer day. It may be nearly white, gray, or incorporate a host of color variations. It seems to be solid and unchanging, but there is evidence everywhere that it has been moved and broken and shaped.

Glacial Valley

A Mount Shuksan glacier lies in a rocky valley under drifting mists

Recently I shared a photograph of the Wheeler Glacier and Cirque located beneath Wheeler Peak in the Great Basin National Park in Nevada. (Yes, I also was unaware that there is a glacier in Nevada…) As I worked on that photograph I had this photograph of a glacier open on my computer. (I don’t know its name — possibly Lower Curtis Glacier?) It struck me just how similar the general features of these widely separated glacier are. Each now consists of an ice field nestled in the bottom of a cirque. Both are surrounded by impressively steep head walls. Both have trees growing very close to the terminus.

I photographed this using a long lens while I was at the Artist Point area at the end of the road to the Mount Baker Ski Area. I had a free day while visiting Seattle, so I did the long up-and-back drive, leaving enough time to photograph in the afternoon. The light may have been less than idea, it being a bit too close to midday, but at times thin clouds muted the sunlight enough to allow light to fill in the shadow details a bit. In addition, some interesting clouds were drifting around the summit of Mt. Shuksan and the occasionally reached further down the peak as in this photograph.

Juniper Forest and a Wash

Juniper trees on red rock soil next to a shallow canyon

My recollection of this afternoon is that we set out down the west side of the park without a particular plan in mind. Eventually we photographed in a deep canyon with tall sandstone walls, but at times we were challenged by trying to find interesting subjects. The light was harsh, but it was also interrupted in awkward ways by clouds — occasionally producing interesting patterns of light and shade, but also sometimes killing the interesting light.

In this area the land slopes down from west to east, following the contours of the underlying strata. For this reason, well before the end of the day the light is already coming across this gently rising terrain at a low angle relative to its incline. Here that light is sweeping across a landscape of red rock, juniper trees, and the beginnings of a small red rock canyon.
