Arches National Park - General Park Information

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.

People have visited what is now Arches National Park for thousands of years. Over time, many different groups have moved in and out of the area in concert with the availability of natural resources and the technology for exploiting those resources.

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.

Arches is located in a "high desert," with elevations ranging from 4,085 to 5,653 feet above sea level. The climate is one of very hot summers, cold winters and very little rainfall. Even on a daily basis, temperatures may fluctuate as much as 50 degrees.

The plants and animals in Arches have many adaptations that enable them to survive these conditions. Some species are found only in this area. The diversity of organisms reflects the variety of available habitat, which includes lush riparian areas, ephemeral pools, dry arroyos, mixed grasslands and large expanses of bare rock.

Summer temperatures (June through September) may exceed 100 degrees Fahrenheit. Winter temperatures (December through February) often drop below 32 degrees Fahrenheit. Temperatures may range 50 degrees in a 24-hour period.
