Nature & Science

The forces of nature have acted in concert to create the landscape of Arches, which contains the greatest density of natural arches in the world. Rock layers tell a story of millions of years of deposition, erosion and other geologic events. Arches is in a "high desert" environment, with hot summer temperatures, cool winters, and infrequent precipitation. The desert conditions determine the kind of life forms that live here, and the park's relative isolation from major urban areas allow us to witness fascinating natural processes and conditions.
