Grand Canyon - Thunder River Trail - rock formation on Esplanade
“A pile of rocks ceases to be a rock when somebody contemplates it with the idea of a cathedral in mind.” Antoine de Saint-Exupery (French Pilot, Writer and Author of 'The Little Prince', 1900-1944)
The Esplanade had many weird & unusual rock formations. These are already cathedrals in my mind. The trail across the slickrock is marked by these little cairns (or "ducks") of rocks.
