Arches Ntl Park - Pothole Arch - May 18, 2010


Arches Ntl Park - Pothole Arch, originally uploaded by kimberzy.

This is an example of a, you guessed it, pothole arch, which is formed by erosion from above. Water running down the edge of the cliff wore a depression (or pothole) into the rock and created the arch. This arch has a span of 90 feet and is 30 feet high, and it is visible from the road.
