Landscape Arch
Arches National Park in Utah, USA
Landscape Arch is the largest natural rock arch on the planet. It is amazingly thin and delicate-looking. 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, yet it supports a span of rock 290 feet long. Pieces of Landscape Arch have broken off during the past few centuries, some chunks the size of automobiles. Indeed, this arch could collapse any day, any year, any decade, any century, that is, any time.
