Arches National Park preserves over 2,000 natural sandstone arches, like the world-famous Delicate Arch, as well as many other unusual rock formations. In some areas, the forces of nature have exposed millions of years of geologic history. The extraordinary features of the park create a landscape of contrasting colors, landforms and textures that is unlike any other in the world. 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. Throughout the park, rock layers reveal millions of years of deposition, erosion and other geologic events.
