Glacial erratics rest on top of a low granite dome in the back-country of Yosemite National Park.

“Erratics” are boulders left behind in the wake of the passage of glaciers, and left behind when the glaciers disappeared. They are found all over the higher elevations of the Sierra Nevada and some of the most striking examples are found in surprising places – like along the top of this granite dome-like ridge in the Yosemite back-country along the Tuolumne River. After spending decades in these mountains I sometimes take these rocks for granted (and for “granite…” ;-), but every so often it hits me just how strange and wonderful it is to find these large boulders sitting in unlikely places.

I made this photograph in the late afternoon as the lowering sun began to cast longer shadows and as earlier clouds began to dissipate above the distant ridges. The Tuolumne River begins it steep descent into the lowlands between my position and the distant ridge covered with granite and trees.

Water and Granite, Tuolumne River

Swift water flows over granite along the bank of the Tuolumne River, Yosemite National Park.

In this section of the Tuolumne River – as in many other places throughout the Sierra Nevada – the river passes through a steep section and across granite slabs that span the full width of the river. As the water flows over the granite it forms constantly changing patterns of rock and whitewater that can only be predicted in general ways. The spot included in the photograph was right along the edge of the river, and you can see the transition between the diminished flow along the bottom edge and the faster and more abundant water in the main channel beyond.

Part of the fun of shooting this sort of subject – and shooting it is a pleasant way to spend an hour along the river – is in trying to find workable compositions in such a changeable subject. And making it even more “fun,” the shutter speed becomes an important decision as it determines just much the image is affected by motion blur and how much of the scene is stopped. Fortunately, digital cameras make this process just a bit more predictable and productive, since they allow the photographer to quickly see the result of composition and shutter speed choices and verify whether or not the educated guesses were correct, and to see just how the infinitely variable and unpredictable patterns of flowing water come together at the instant of exposure.

Forest and Granite

Forest trees ascend a slope filled with small granite domes and ledges, Yosemite National Park.

This little scene could probably be found in a few thousand locations in the Sierra if you were to keep your eyes open while wandering about. The combination of glacially-smoothed, rounded granite formations, a bit of meadowy grass, and groves of pines is a distinctly “Yosemite” sight for me.

I photographed these trees in a location not far from the Tuolumne River where a side canyon comes down from above to join it. From a somewhat open position along one side of this valley I was able to shoot across the valley with a slightly long lens and compress the distance a bit and pick out a series of granite diagonals interrupted and hidden by the back-lit trees.
