Double Arch Sunday.
Everybody has their threshold for arch-viewing, and about mid-afternoon we decided, Okay, we've had enough. But we wanted to squeeze just a little more archiness into the day, so we made one last hike to Double Arch (not to be confused with Double O Arch) in the Windows section of the park. The first picture isn't of the whole thing, as I couldn't find an angle that I liked. But this shows one of the arches, silhouetted against the afternoon sky.
This arch is more elaborate than the name "Double Arch" might imply. From the top of a wide, triangular fin of sandstone, erosion has carved a deep hole – and then punched large arches through two of the walls bounding the hole. Standing in the middle, you are effectively at the bottom of a wide well, with an arch on either side of you.

In the bottom picture, you can (if you look carefully) see both arches, plus a little bit of sky showing through from the top of the "well".
Also, you can see more incipient arch formation off to the right... Entrada sandstone just isn't happy if it can't make an arch.
This arch was used in the beginning sequence of one of the Indiana Jones movies – though the train sequence immediately following was filmed one state over.
