The fractured and bent layers of a fractured boulder in a Utah slot canyon.
This jumble of rocks sits in a Southern Utah canyon, piled on debris and the lower face of a cliff that runs along the banks of a small creek. The bottoms of such canyons are, for obvious reasons, places full of all sorts of debris that either falls from the surrounding cliffs or is washed down the canyon in periodic floods. A good part of the challenge of making progress through such terrain involves contending with this detritus.
As is so often the case in these landscapes, the initial appearance of features may mislead the viewer about their history. Rocks, of course, seem quite solid and immutable. But this little vignette of almost nothing but rock actually shows more about how much it changes than about its stability. This rock was formed in layers laid down by water a long, long time ago. Those layers were compressed, folded, upended and broken over time. Here we see a snapshot of that process. Lying atop a smoother section of the cliff, this deteriorating boulder’s layers are made apparent as they break apart and realign.
