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.

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.
