Granite slabs littered with exfoliated boulders, Yosemite Naitonal Park.

As is our pattern in the backcountry, by late afternoon each of photographers in our group had “headed out” find subjects to photograph in late-day light. There was a lot to work with in the area surrounding the lake where we were camped; low ridges, the shoreline of the lake, forest, meadow with boulders, granite slabs, and even actual mountains if you walked far enough.

I decided to wander to the other side of our lake, where a granite dome rise above the water… and dropped of precipitously into a gigantic canyon on the other side. I decided that I would approach from one side, cross the summit close to sunset, and then return to camp by descending a ridge on the other side. The angle of the light was quite low as I crossed granite slabs to a low spot between the dome and another low hill, and the slabs were covered with boulders that appeared to be remnants of the process of exfoliation.

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.

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.

Morning light on trees and glaciated ridges, Yosemite National Park.

It is now 11:23 p.m. PDT on Friday, August 12… and I just realized a few moments ago that I neglected to schedule the posting of a new photograph today! Before I left for Yosemite on this past Wednesday I thought I had placed a photograph in the queue for automatic posting today, but apparently not. As long as I complete this post in the next half hour or so, I won’t miss posting my daily photograph!

I made this photograph early today (Friday, August 12) as the first light was striking the glaciated ridges near Olmsted Point. I had arrived early enough to climb far up on the granite slopes above the famous overlook before the sun came up – I had a plan to photograph some of the solitary trees high on these granite slabs as the first light struck them. I accomplished that, and as I began to descend from this area I decided to make a few more photographs while I was up there. Across the nearby canyon is another ridge that is topped by the glacial erratics, the solitary boulders sitting on top of the rounded ridges and just about anywhere else in this part of Yosemite. The early light was coming across from the left and striking the tops of these ridges, but it had not yet struck the huge face of Clouds Rest, seen behind them.
