Sand Tufa, Mono Lake

July 19, 2012 G Dan Mitchell Leave a comment

Early morning light on details of sand tufa formations, Mono County.

I have wanted to photograph this subject for some time. The sand tufas are not found in the same location as the better-known “tufa towers” that are so often photographed, and they are smaller and somewhat subtler (if that is the right word) subjects. If you weren’t aware of what you were looking for, it would be very easy to pass right by them and barely notice their presence at all. They also appear to be very fragile, so great care should be taken if you ever happen to come across them. Walk around, not over or through them, and minimize your impact on them to the greatest extent possible. If you come across examples, it is probably best to not blast a lot of specific information to the world. I don’t know all of the details of their formation, but judging by their locations and by the recent history of lower lake levels, I suspect that they may have been underwater before the historically recent extraction of water from the eastern Sierra by Los Angeles.

If you are thinking of looking for an interesting and easy to shoot photographic subject, don’t bother with the sand tufa. You’ll probably have much better luck and more fun shooting the impressive and better known and larger “tower” features at other areas. These small structures do not tower above anything. Some are only inches tall, and the largest are just a few feet tall. Their natural color is a muted and, let’s be honest, boring gray color. Their location does not particularly allow them to be paired with more impressive and distant large-scale landscape features such as the expanse of the lake’s surface or the surrounding mountains and hills, with the possible exception of certain kinds of cloud formations. When I went there I had some pre-conceived ideas about I might photograph them, perhaps including the Sierra’s eastern escarpment in the images, but these ideas did not pan out. However, by shooting in the first few minutes of light and working with a long focal length to crop tightly I found some interesting fluted patterns to work with.

Murphy Point, Sunset

May 25, 2012 G Dan Mitchell Leave a comment

Sunset light on Murphy Point, photographed from Green River Overlook, Canyonlands National Park.

We spent the better part of a day scouting around the “Island in the Sky” section of Canyonlands National Park, partly with the goal of figuring out where to be for golden hour light. In the end, the very first place we had really considered ended up being the place we came back to – the Green River Overlook. While quite a few landscape photographs can be somewhat spontaneous and a matter of quickly taking advantage of ephemeral conditions, the decision to photograph at the Green River Overlook was quite the opposite. Not only had I decided that I wanted to shoot at this location, but I had even worked out the composition of the shot that I wanted.

With that in mind, we came back here almost an hour before actual sunset, confident that the photograph I had in mind would be waiting for me. And it was! That photograph was shot looking roughly west or a bit south of west and across the canyons dropping into the Green River. But I also had quite a bit of time to look around at other possible subjects as the light slowly transformed. The steep upper cliffs of (what I believe to be) Murphy Point stood to my south and the sunset light began to intensely color their red rocks during the final few minute of sunlight. So I took a moment away from the shot I had come for, pivoted the tripod this direction, and made a few exposures. The geology seen in this area is amazing. Layer upon layer build from the bottoms of the river canyon, through the side canyons and onto the lower plateaus. Then shattered rock stacks up against the tall upper sandstone cliffs that are topped by the relative flatlands of the “Island in the Sky” area. Here the low angle side-light from the setting sun reveals a lot of the more subtle details of this landscape.

Sandstone Towers, Moon Rising Through Clouds

May 24, 2012 G Dan Mitchell Leave a comment

The full moon rises in a cloudy sky above sandstone towers, Arches National Park, Utah.

These rocks are near but not exactly part of the windows area at Arches National Park, where we ended up at the end of our first day there. We had arrived in Moab in the afternoon and then driven up into the park very late in the day – more or less gasping in amazement at the geology we were seeing for the first time – and finally ended up in this area just before sunset.

I’m repeating a story I wrote about earlier, so I’ll make the first part short. There was beautiful light leading up to sunset, and there were some interesting clouds in the sky to the north. However, it was extremely windy, making longer exposures as the light faded a real challenge and also making lens changes unwise. After sunset I ended up in the shelter of some rock towers where I found some protection from the wind. I knew that this was going to be a full moon night, but I was a bit concerned that by the time it was high enough that the ambient light would be somewhat dark, making it very difficult to photograph the twilight surroundings and the very bright moon in a single exposure. But as the moon rose and I found a location from which I could position it and the rocks together, high thin clouds partially obscured the moon and allowed my longer exposures for the dim foreground to work. I might have used a longer lens, but the thought of changing lenses in the blowing wind convinced me to just go ahead and shoot with the lens I already had on the camera – and in the end I think that let me produce a more natural view of the moon than I might have achieved with a longer telephoto.

Sandstone Towers, Early Evening

May 21, 2012 G Dan Mitchell Leave a comment

Early evening back-light on sandstone towers and desert terrain, Arches National Park.

I made this photograph within minutes of entering Arches National Park for the very first time. I have written before that this was my very first time photographing in Utah – yes, embarrassing, but true! The downside of this is that I now really wish that I had taken the time to travel here much earlier. But the upside is that I had the rare experience of encountering a completely new and, for me, unanticipated landscape for the first time.

Before departing for Utah – where we visited a veritable smorgasbord of locations – I had done almost no research beyond figuring out where the nearest lodging was. In fact, even once we were in the state I was still figuring out how to get from one location to another. There are perhaps several reasons for this approach, but one was that I do not necessarily want to go to a new place with overly strong ideas about what I should photograph nor about how I should photograph it. I prefer to get there, look around, try to get the “feeling” of the place, and begin making the photographs that I see. We arrived in Moab late in the day and checked into a motel. There was still some light left so we figured we should go somewhere… and Arches is very close! So the decision was made, and off we went. By the time we reached the Park Avenue area not far from the entrance I was stunned by what I was seeking. (It helped that we arrived at the beginning of “golden hour,” but I digress…) There were huge sandstone walls, thin fins of rock, tall towers, some with boulders perched on top – this seemed about as close to an “impossible landscape” as any I have seen. Frankly, it was overwhelming. We passed Park Avenue and drove ahead a bit to where the view opened up to this astonishing panorama, at which point we pulled out and I began making photographs, including this one that includes towers and fins backlit by the late afternoon light under thin clouds.
