Canyon Wall. © Copyright 2012 G Dan Mitchell – all rights reserved.
Broken boulders and strata at the base of a slot canyon wall.
These canyons are simply full of fascinating details. Unlike much of my familiar Sierra Nevada landscape, where vistas can often go on for many miles, here the size of your world is much smaller. It is constricted to the width of the canyon, the distance to the upper rims (plus some sky), and upstream and downstream to only the next bends. So you are almost forced to focus on smaller details, of which there are many.
Here my attention was drawn to the rocks. I’m no geologist, and I only know enough to speculate about these things. But a close look at the rocks in this scene show material that was created in layers. Near the upper right corner, if you look closely, you can spot a place where there is a striking convergence of angles in the strata. And although this material was laid down in horizontal layers, over time it has been pushed and stretched and lifted until the formerly horizontal now angles up distinctly to the left. There is also an interesting almost vertical fracture between the more solid (and darker) rock on the right, and the lighter color of the broken rocks stacked up on the left.
