Delicate Arch:
Carved in Entrada Sandstone, this free-standing arch is composed mostly of the Slick Rock Member. The top is a five-foot thick layer of Moab Tongue. A remnant of an ancient fin, the arch today has an opening of 45 feet (13.7 meters) high and 33 feet (10 meters) wide.
Water and time have sculpted Delicate Arch, and erosion continues to slowly wear away the features of this mature span. Although it will eventually succumb to the same forces that created it, this majestic arch now stands as an iconic feature of the American West. |
