Arches National Park
Arches National Park
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.
Rocks have attracted visitors to Arches National Park for thousands of years. However, sightseeing has not been the main activity for very long. Hunter-gatherers migrated into the area about 10,000 years ago at the end of the Ice Age. As they explored Courthouse Wash and other areas in what is now Arches, they found pockets of chert and chalcedony, microcrystalline quartz perfect for making stone tools. Chipping or knapping these rocks into dart points, knives, and scrapers, they created debris piles that are still visible to the trained eye.
Climate: Southeast Utah is part of the Colorado Plateau, a "high desert" region that experiences wide temperature fluctuations, sometimes over 40 degrees in a single day. The temperate (and most popular) seasons are spring (April through May) and fall (mid-September through October), when daytime highs average 60 to 80 F and lows average 30 to 50 F.
Summer temperatures often exceed 100 F, making strenuous exercise difficult. Late summer monsoon season brings violent storm cells which often cause flash floods.
Winters are cold, with highs averaging 30 to 50 F, and lows averaging 0 to 20 F. Though large snowfalls are uncommon (except in nearby mountains), even small amounts of snow or ice can make local trails and roads impassable.
