Natural forces created the landscape of Arches, which contains the greatest density of natural arches in the world. Rock layers tell a story of deposition, erosion, and other geologic events. Arches is in a "high desert" environment, with hot summer temperatures, cool winters, and infrequent precipitation. Desert conditions determine the kind of life forms that live here. We can witness natural process and conditions thanks to the park's isolation from major urban areas.
