Dynamic Erosion
I took this image because of the stunning geology featured. The rock was in the floor of the Grand Wash, one of two deep but easily-accessed canyons along the scenic drive at the centre of Capitol Reef National Park in Utah.
Grand Wash offers a pleasant, safe introduction to narrow canyon hiking, although even here there are prominent warnings of the dangers of flash floods, and the rock above clearly shows the effects of such fast-flowing water (travelling from right to left), which was presumably carrying varying sizes of rocks, pebbles and grit helping to grind down the materials seen in the image.
The wash cuts right through the reef and features sheer cliffs of Wingate and Navajo sandstone up to 150m high, with many colourful strata and eroded rock formations. There is a short, enclosed section of the streamway where the walls are less than 5m apart and the waters, when flowing, cover all of the canyon floor.
The location above was in a narrower section. I put the (very old-school) film can on the feature to give some scale. The boulder seems to feature two different types of rock, with the fine darker and harder (igneous?) rock coming through in small bands.
I'm not sure which specific rock types these are, but I felt the striking results of the erosion deserved to be recorded.
The exact location along Grand Wash Road is arbitrary as I can't remember exactly. The image is scanned from a colour negative and processed in Lightroom, Photoshop and Silver Efex.
