A freestanding sandstone arch shaped by wind and water/Geology & Minerals
Delicate Arch in Arches National Park, Utah, is perhaps the most famous natural arch in the world and appears on Utah's license plates. It stands about 16 meters tall with an opening roughly 10 meters wide and 4 meters deep. The arch is made of Entrada Sandstone, deposited about 150 million years ago. Erosion from wind, water, and frost created its distinctive freestanding shape over millions of years. Geologists estimate it could collapse within the next few thousand years.
