Sadly, the author has learned that this arch has collapsed.
If you would like to check this out, turn left onto the Potash Mine Road(Rt. 279)
from Rt. 191 north of Moab. This is a good paved road as far as the Potash Mine
where it becomes gravel. This is ostensibly a two-wheel-drive road, but at
least a high clearance vehicle is recommended. Continue on this road past the
Potash Mine buildings and keep an eye out on the right for the fallen arch.
See Backside of Sally's Arch showing how it appeared from the rear.
Also see Sally's Fallen showing how it appears after collapsing.
