During a week-long stay at a backcountry Yosemite lake my partners and I had plenty of time to explore our surroundings. A day in such a place is a joy, but we had a string of such days, with conditions ranging from Sierra blue sky, through wildfire smoke, to an early seasons autumn storm that dropped rain on us for a couple of days.

Being in one location for so long provides the opportunity to really get to know the place. After a day or so getting to know the main, iconic features, continuing exploration beings to reveal things that we miss at first. Across the valley from our camp was a long and low rock wall, at the base of steeply sloping granite walls and holding somewhat level basin. Not surprisingly, the evidence of water flowing over this wall was obvious, from the lush plant life to the  beautiful water stain patterns.

During our week camped at a Yosemite back-country lake in September we had plenty of time to become intimately aware of the surrounding landscape, to explore its features, and to return to some of them more than once. One photographer who wasn’t with us this time but who has been a fixture on these trips in the past (Hi, Mike!) and shared some general information about a particular feature that intrigued him — and as a result the rest of us also became intrigued by it. The description of the location was a bit vague, but not so vague that a person who knows the area well would be unable to find it. (Think of directions like, “Near some granite to the south of a lake and west of another lake.”) So, once on the scene, this area was one that caught our focus.

Up from where we were camped, through some trees, and near the base of an incline, there is an odd section of cliff. In the sort of spot where you might expect everything to have been ground away by ancient glaciers there is a section of cliff that is hundreds of feet long and perhaps no ore than thirty feet high. A basin lies above it, and it seems that water finds many places to seem over and through these rocks, staining them in all sorts of diverse and amazing ways. This photograph is one of several close up studies I did of small sections of this face, where solid, blocky granite is cut through by cracks and water stains are everywhere.

Backcountry Lake, Dawn

Another morning from a week of such mornings at this Yosemite backcountry lake. My tent was at the end of a granite slab leading back up from the shore of the lake, so it became typical to arise each morning, crawl out of the tent, grab camera and tripod, and walk the slab and then the meadow beyond to the shoreline for morning photography. In this strange weather year in the Sierra every morning was different. One morning it might be clear, another was filled with thick wildfire smoke, and on yet another it was raining.

This was an in-between morning. There was a bit of wildfire smoke — it never went away completely during our stay — and high clouds muted the morning light on the lake itself. The air was not moving, and was September-cold. First light brought a bit of color to the clouds, reflected in the early morning stillness of the lake.

Basalt Columns, Lichen, Autumn Plants

Quite honestly, this photograph was at least partially the product of laziness! We were recently in the eastern Sierra Nevada for a few (more) days of autumn color photography. We had driven up late the previous day, and by the time we got settled in to our lodgings the idea of getting up again at “oh-dark-thirty” to head out and make dawn photographs was not appealing. Rather than overtly cop out, we sort of agreed to maybe not set alarms and instead just sort of see when we might wake up. Needless to say, on the morning after a very long drive that ended late at night… we did not get up at the crack of dawn! In fact, we wandered out for breakfast at perhaps 7:30 or so, and only then returned to our room to get ready for photography.

With no prior planning at all, we made  a more or less spontaneous decision to visit Devils Postpile National Monument, which was convenient to our lodgings at Mammoth Lakes. I’ve been in that area many times, but always in conjunction with backpacking trips, and most of those simply headed out from Agnew Meadow. We finally got down there in the middle of the morning. It turns out that this is actually a very good time to photograph this geological structure, as the sun is behind it, producing beautiful soft shaded light on the details of the basalt columns. To make a series of photographs from which this image comes, I used a very long lens, which allowed me to isolate and compose photographs out of small areas of the much larger wall of basalt columns. (Update — December 2015: Patty Emerson Mitchell reminds me that I almost left my camera in the car on this morning, claiming that I was really just there to let her see this location!)
