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.

Three glacial erratic boulders atop a granite dome near Glen Aulin, Yosemite National Park.

Looking for something to photograph one evening during my September back-country photography trip into the Glen Aulin and McCabe Lakes area of Yosemite National Park, I climbed up from our camp site to the top of this small granite dome or “whaleback” above the valley of Glen Aulin. The dome is merely the most open and exposed portion of a ridge of more durable rock that rises a ways up the slope from near where we were camped, and from its “summit” I had a 360-degree panorama of the surrounding landscape as the day came to an end.

When I first arrived at this spot more than an hour earlier, the sky was almost completely clouded over. This was one of those situations in which the immediate photographic prospects seemed quite limited, with gray skies and murky atmosphere, but with some potential for interesting things to happen if the clouds thinned as sunset approached. So I decided to stick around in this spot rather than wandering around looking for something else, and in the end the clouds did thin. Before I made this photograph, one of the last of the evening, I had managed to find a range of subjects as the light changed: the light from breaks in the clouds began to move across a forest to my right and light a small prominence nearby; light coming over the ridge at the far right back-lit some haze behind trees on a lower ridge that was closer to me; and finally the remaining clouds took on a bit of color right as the sun dropped below the horizon.

Stones, Stained Granite

Granite stones rest on glaciated slab of stained granite near the Tuolumne River, Yosemite National Park.

Scared you, didn’t I? Thought I was going to miss posting a daily photograph, right? Yeah, both of you… ;-)

In any case, I may have mentioned previously that I’m a sucker for Sierra granite, especially the glaciated kind that is found almost everywhere you go in Yosemite National Park, from the Valley to areas surrounding the very highest peaks. (Some of the highest peaks escaped the glaciation themselves, but that’s a longer story for another time.) For me, some combination of glaciated granite slabs, a few “erratic” boulders (“erratics” being boulders moved from their source and left behind by retreating glaciers), some trees, and a bit of meadow grass, perhaps with a stream or lake nearby shouts “Sierra Nevada.”

This photograph does not include all of these Sierra ingredients but it does include the granite. I photographed this small bit of granite slab along a section of the Tuolumne River than runs through the back-country during a week-long backpack trip this past September. Something about the arrangement and color of the four larger stones against the water-stained underlying rock with its complex textures interested me. A lot of what is in the frame may not be visible in the small jpg version posted here, but there is a lot of detail in the frame: the texture or rock, crystal structures on some of the stones, several smaller pebbles, even a bit of dried pine needle.

Various rain-moistened plants growing in a fracture in lichen-encrusted glacial granite slabs, Yosemite National Park.

This photograph was made in almost exactly the same spot as the photograph I posted yesterday, in an area of water-stained granite along the Tuolumne River in Yosemite National Park. Not only was I fortunate to have soft light, but it was cloudy and it had been raining lightly just before we went out to shoot. You can’t ask for much better conditions for such a subject: soft light from the clouds, colors saturated by the moisture, and a few small drops of rain still on the leaves of the plants. (The latter may not quite be visible in this little jpg image.)

I’m always on the lookout for this little intimate landscapes, especially if they include Sierra granite. I had been wandering around this area trying to find ways to make compositions out of the reddish and rain-moistened rock, shooting trees and small plants and even a few isolated rocks. This plant was growing out of a narrow crack and hanging downward, its green contrasting with the reddish-brown color of the rocks . The arrangement of the nearly vertical crack, the diagonal boundaries between the red rock and the gray rock, and the mottled texture of the lichen also caught my eye.

When I share a photograph like this one, I’m reminded of my friend Mike, a retired Yosemite ranger, who pointedly reminded me once that sometimes there really is no good reason to name the precise location of such a scene. The location is irrelevant to the photograph, similar little scenes are repeated thousands of times over throughout the Sierra, and it isn’t really about the specific place at all.
