Either that is an awfully large coin, or this is a very small
arch. Actually this formation does not qualify as an arch;
but it looks more like an arch than some real arches.
Based on the size of a quarter, the "arch" has less than a
one foot span. It is located in a side canyon along the
paved road to "Mouse's Tank" (see the map in the hand-out
available at the Visitor's Center).
