'Stegosaur in Buckskin Gulch.’

	The spectacular ‘polished’ walls of the Buckskin Gulch, a branch canyon of the Paria River, are formed during flash floods as stones and pebbles hit the walls at great speed. At some points they seem to resemble the scaly back plates of a Stegosaur. Photo Mick Palarczyk.
