Located in SE Utah, on 73,379 Acres, Arches National Park has 2,000 cataloged arches, the highest concentration in the world.

Over 100 million years of erosion created an awe-inspiring landscape of fins, arches, balanced rocks and petrified dunes of sandstone.

Constantly under attack by geological forces, over time, the arches will collapse, new ones will form and balanced rocks will fall. These sandstone arches and monoliths are transitory, occupying a millisecond on the clock of geological time.
