Landscape Arch, Arches National Park
Landscape Arch is the longest of the many natural rock arches in this national park and second longest in the world.
This arch is an arc natural arch eroded in Entrada sandstone. Arc natural arches are considered old and near the end of their lifecycle. It is hard to believe that a piece of rock like this can exist. In its thinnest section the arch is only 6 feet thick. Indeed, this arch could collapse at any time: any day, any year, any decade, or any century.
