Not less than 950 arches are hidden in Arches National Park in Utah. Undoubtedly none of them is as famous as the stand-alone Delicate Arch. The reason that this fragile beauty can be adored today is hidden in the complex geology of this region. Here, the perpetual forces of precipitation and wind eroded about 1600 m of bedrock sediments. Today these arch forming sediment layers of Jurassic age, about 140 million years old, are exposed at the surface.
