I photographed this interesting geological structure while hiking in Tennessee, at Piney Falls State Natural Area. Located on the ceiling of an overhang from a gorge-wall, these outcroppings represent the end result of erosion, where small amounts of water seeping through sandstone over time have deposited minuscule amounts of mineral – creating these downward structures – before succumbing to gravity; whereby a scattered array of indentations in the hardened ground may be observed.
Or, so it seems. I’m not a geologist, but do sell photographic prints at Pixels.
Drop by for a visit, sometime!
