RHH's photos with the keyword: pothole arch

The photo shows the reason for the name of this arch, which can be seen outside of Arches National Park along the Corona Arch trail. The trailhead is along the Potash Road west of Moab, Utah. This type of arch is called a pothole arch. It was formed when a pothole on the ledge above gradually merged with an alcove in the rock face below through the actions of water and debris. It is a fairly common type of arch.
