Trees on Granite Ridge

Rugged trees growing along the top of a glaciated granite ridge, Yosemite National Park

I made this photograph on my first visit of the season to the Tioga Pass area of the Yosemite National Park high country. I managed to be there on the first and second open days. This was an unusual though perhaps not unprecedented sort of opening, in that there was a record low amount of snow in the Sierra as the warm season began, and this was the second of two back-to-back low-snowfall winters. This season was an odd one. I was in the Sierra back in early fall and it seemed like we might actually have an early and wet winter. Certainly things played out that way through the end of 2012 – but then the tap was shut off and there was precious little precipitation at all during the first part of 2013. As you can see in the photograph, there was still some snow around, but it looked more like late June or even early July of a more typical year.

The photograph was made near a very popular location along Tioga Pass Road, though I walked more or less the opposite direction from the objects of everyone else’s interest to find a vantage point that let me photograph back across this granite ridge, littered with glacial erratic boulders and the debris from exfoliation, and supporting a few trees. The morning light slanted in from behind the ridge and the trees and left a bluish haze between this ridge and the even larger granite ridge across a deep valley.

Granite and Trees, Morning

May 13, 2013 G Dan Mitchell 3 Comments

Morning light on granite slabs in the Yosemite high country.

These are the light, the rocks, the trees that bring me back to the Yosemite high country of the Sierra Nevada every year when Tioga Pass opens and which keep me coming back until the high country closes again in the fall. Tioga Pass opened for the season this past weekend, and that – plus the chance to see a show and visit with some friends in the Valley – was excuse for a quick visit. I try to go over the pass each season on the day it opens or shortly afterwards. For me, crossing that pass and starting down the road into Lee Vining Canyon marks the start of “summer,” even though the calendar still says it is spring.

Since the high country camp grounds are not open yet and the Forest Service camps east of the pass are also still closed, I ended up getting a last-minute camp site in Yosemite Valley. (This also provided the opportunities to attend the reception for John Sexton’s and Anne Larsen’s show at the Ansel Adams Gallery, to hear John’s wonderful talk about Ansel Adams that evening, and to get one last crack at photographing this year’s dogwood bloom.) On the first day I did little more than make an obligatory drive up toward the pass and see the familiar country. This was the second dry winter in a row in California, and there is very little snow for such an early date in the season. Perhaps because of this, there were far fewer people up there than on other recent opening days. On the second day I got up well before dawn and left my Yosemite Valley camp in darkness, driving up Tioga Pass road early enough to photograph in the May Lake (turnoff), Olmsted Point, and Tenaya Lake areas in early light. Here I found what I was looking for – sparse trees in the back-light from early morning sun, ridges of exfoliating granite, and a bit of hazy morning atmosphere. I suppose it might just be my first high-country photograph of the new season.

Glacial Erratics, Near Olmsted Point

October 11, 2012 G Dan Mitchell Leave a comment

Glacial erratic boulders rest on a tree-topped granite slab at sunset near Olmsted Point, Yosemite National Park

Among the various landscapes of the high Sierra, this sort of scene most clearly says “Yosemite” to me: the glaciated granite slabs, mostly solid but broken but exfoliating and broken by cracks; the scattered glacial erratic boulders left behind by retreating ice; and the sparse trees somehow managing to not only survive but seemingly prosper while growing on almost solid rock. Although you don’t see precisely these things in the better known Valley, once you get up into the high country of the park you’ll see these features almost everywhere, and especially in the zone from, say, 8000′ of elevation or so and on up.

This photograph was made close to Olmsted Point. While Olmsted is probably better known for its “backside” view of Half Dome and its huge views up toward Tenaya Lake and on to the Sierra crest at Mount Conness, the immediate surroundings are full of this typical Sierra terrain that I described above. Most of the terrain above, below, and around the Point shows evidence of this glacial action, and by taking a few steps away from the parking lot in almost any direction (but do avoid cliffs!) you can find enough examples of this landscape to keep yourself occupied for a long time.

Plants, Granite, Morning Light

August 31, 2012 G Dan Mitchell 2 Comments

A few sparse plants grow in thin cracks in granite slabs, Yosemite National Park.

Portions of the Sierra high country in Yosemite have been heavily glaciated. The evidence is widespread and familiar in all of its variations: domes, U-shaped canyons, remnant glacial ice-fields and a few vestigial glaciers, glacial erratics everywhere, a terrain crossed with the remains of lateral, medial, and terminal moraines. And it places, such as this area along Tioga Pass Road, there are huge expanses of granite slabs, sloping and rounded nearly solid rock broken by cracks and dikes and surrounded by the debris of gradual erosion.

Lots of things managed to live on and in these slabs. The tiniest cracks collect sand, then dust and gravel, and soon small plants spring up and even wildflowers. In some places – including the more distant ridge in this photograph – large trees manage to sustain themselves by growing entirely in these cracks. In this photograph I juxtaposed the nearby small plants crowing in a couple of shallow cracks with the receding sequence of rolling dome-like ridges with shattered rock and a few trees, some of which catch the early morning sun, with details softened by the (perhaps unusual, for landscape photography) use of a small aperture to minimize depth of field.
