I found a site at Goose Island Campground right by the Colorado River near Moab. It is just a couple of miles drive to the entrance to Arches.
Broken Arch is not really broken, just that they say that it looks broken from a certain angle. I couldn’t see it.
Delicate arch is the symbol for the state of Utah. It is also used on some of the license plates.
The second arch of Double O is the smaller darker circle below the main arch.
