Red on White, Sandstone

December 21, 2012 G Dan Mitchell Leave a comment

A vestigial layer of red sandstone forms small, layered mounds atop patterned white rock, Zion National Park

All over the southwest, where various layers of sedimentary rock meet, it is possible to find odd and surprising juxtapositions of the different layers. In many places a bit of a higher, harder layer will remain above the softer material below, creating hoodoos and mushroom-shaped structures. Sometime the upper rim of a canyon will be lined with a layer of the harder rock, while there is a steep drop-off below. Here, bits of the darker read sandstone, with different types of layering and different texture, sit on top of the smoothly curving and finely layered underlying lighter rock.

I had seen this spot in Zion in the past – it isn’t all that hard to find – and even photographed it from a greater distance and different angles. This time I decided to approach more closely, walking out on the wave-like formation of the lower, lighter rock and passing around these small reddish prominences. I made this photograph on the same day I made many of my other most recent Zion photographs, a day when the light varied tremendously due to winds and cloud cover. One moment this spot was hit by brilliant sunshine, and a moment later it was in shade – and the changes did not always synchronize between the near and far elements. I made this photograph during a moment when the direct sun was largely muted by passing clouds.

Sandstone Patterns, Dried Plant

A dried plant and sandstone patterns in a southwest desert canyon, Utah

I was in Utah twice this fall, most recently with my friends Charlie and Karl to photograph a range of desert canyons and similar terrain. I’ve written before that I’m very new to photographing Utah, having seriously shot there for the first time only this past spring. But I’m trying to make up for lost time! Overall, I have spent something like a total of more than five weeks there this year! Yes, I like shooting in Utah. :-)

On the previous visits, I went to quite a few of the well-known locations – largely the national parks – and began the process of getting to know and understand that place a bit. On the most recent visit I was fortunate to be traveling with people who have shot there for decades, and I benefited from their long experience. Getting a bit more off the beaten track, we barely touched national parks – passing through Zion and visiting some remote areas of Capitol Reef. Instead we poked into a range of little canyons and valleys and so forth that don’t have the prominence of the parks. The specific locations are perhaps not that important since the state seems to be filled with similar places. This was my first real experience with the intimate desert canyons and river/creek courses that carve deeply into the landscape, where midday light bounces and reflects into the deep landscape in ways that are utterly unlike the California locations where I most often photograph.

This photograph was made in such a place, the first narrow canyon that we visited. Parking in an inauspicious spot along a gravel desert road, we dropped into a wash and wandered upstream, soon entering a narrow canyon as the sandstone walls rose beside us. Before long the canyon was narrow enough that we had to continually cross back and forth across the creek or simply wade straight up its course. As the canyon narrowed, direct sunlight no longer made it down to the creek – instead the light reflected from the higher cliff faces and bounced down into the canyon, toning the light red from the sandstone surface. In this photograph the cliff and two large pieces of sandstone contain angled strata and reflect the light in various ways as a small and seemingly dead plant sits in a crack in the rock.

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.

Ledge With Fallen Rocks

September 10, 2012 G Dan Mitchell Leave a comment

Red cliffs and rocks on a ledge at Park Avenue, Arches National Park.

I made this photograph fairly early in the morning at the Park Avenue area of Arches National Park. While morning might was hitting the walls behind my camera position, the walls in front of me were still in fairly deep shade. However, as the sun rose, its light began to come over the tops of these tall sandstone walls and spill down into the canyon. As the morning wore on, the light/shadow line began to move back closer to this wall, first illuminating the ledge and the fallen rocks in holds and then beginning to highlight edges of some of the cracks in the wall itself.

The Park Avenue area seems like one of the most accessible areas of this park being only a short distance inside the park boundaries and being very close to the roadway. The area is essentially a canyon between two nearly parallel walls of sandstone, often topped with remarkable towers and other features as the canyon descends toward where it opens up into sage brush country below. At this particular hour of this particular morning, as wonderful as that scene was, the light shooting down the canyon was only so-so, so I looked around, put on a long lens, and photographed smaller vignettes of the landscape such as this one.
