POTD: Flying Buttress

Flying Buttress
Death Valley National Park, California

A very unusual arch or widow. (It’s not always clear to me how the two differ.) It looks like it was from two pillars that leaned towards each other and then fell over at the same time, forming the arch in the process. But that would take a rather remarkable feat of geological timing, so I suppose it’s more likely it was formed as a unified arch first and then started to fall apart due to further weathering of the fissured rock.  On the other hand though, it’s quite a remarkable feat of geological structuring and weather just to get an arch to form in the first place, so who knows.
