Dark hills contrast with surrounding salt flats and alluvial fans

I know that “dark hills” is not a very poetic description for this landscape… but it does seem, at least, to be accurate! These formations have intrigued me for a few years, and I’ve been surprised to be able to photograph them all alone — despite visiting them regularly, I have never encountered another person there. I’m not sure why, except that there are some better known icons nearby, and perhaps they attract all of the others in the area.

In the past I tried to find out more about the source of the formations and my recollection (which I was unable to re-verify this time) is that they are the result of some kind of ancient tufa-like deposits formed on the bottom of the lake that once filled the basin that is now Death Valley. Their darker color contrasts strikingly with the surrounding terrain, and the material of the mounts has a finely layered quality. This example sits on a small playa where pooling water seems to have left salt deposits behind, though similar forms can also be found in slightly higher terrain nearby. In the evening the low light from the west angles across these mounds and makes their textures and curves a bit more visible.

Three Towers, Morning

In mid-July I was in the Tuolumne/Tioga Pass area of the Sierra for a few days of photograph. In the end, I decided to stay over one extra night so that I could drive down to photograph around Mono Lake early in the morning before heading home. I was up before dawn, quickly in my car, and down to the shoreline of Mono Lake before sunrise. My first objective was to try to photograph sand tufa formations – not the more famous tufa towers. I found what I was looking for, and spend the sunrise period photographing them in first light. However, this opportunity quickly ended, so I turned my attention to the lake itself, along with its surroundings of low hills.

While the tufa towers are the iconic visual symbols of Mono Lake, I have some other and perhaps strong associations with the place. Most of them are connected to a time of day, early morning, when I most often visit. They involve near silence, broken only by the sounds of the many gulls and other birds that are found in and around the lake. In my memories, the air is still, and it is warm, the warm of early an early desert morning that holds the smell of sage and dust. And while the moment of sunrise is what I often go there to find, in the end it is the light that comes a bit later that sticks most in my mind. This light is bright – almost too bright to look into if the lake is hazy – and it is blue with distance. This is the light that I saw on this morning, with a bit of very light breeze forming slight patterns on the surface of the lake near three isolated tufa towers.

Sand Tufa, Mono Lake

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.

Pastel shades of purple and blue just before dawn at Mono Lake.

Back at the end of 2010 I wrote that I was going through all of my 2010 raw files to look for images that I had passed over, as I do near the end of every year. Things got busy, I got distracted, and I only got about half way through the year’s files. Recently I have returned to the 2010 photographs to try to complete the task, and this is one of the photographs that I rediscovered as I resumed the search with images taken near the end of June.

This was my first real photographic trip to the Sierra during the summer season of 2010. I had made a brief trip up there, visiting Yosemite Valley and then crossing Tioga Pass, back in early June right about the time that the pass opened. However, on this trip I was able to spend several days in the high country and kicking around near Mono Lake. This can be a great time of the year up there since conditions range from what seems like late winter in the high country to real summer in places like Owens Valley and around Mono Lake.

On this morning I decided that I’d head down to Mono Lake well before dawn and see what I could turn up. I did not go to the iconic South Tufa area on this morning, thinking instead that I’d try for some different and longer views of the lake. (Later in the morning I traveled a good distance south of the lake on the less-used section of highway 120.) There were, obviously, clouds in the morning and they blocked the sunrise. However, the light glowed through and over and under and around them, and even though there was not direct light in very early morning image, the colors were quite something. The group of tufa towers at the lower left are offshore not far from the South Tufa area.
