Mesa Arch

Mesa Arch is a natural stone formation on the eastern edge of the Island in the Sky mesa, offering views of Monster Tower, Washer Woman Arch, and the La Sal Mountains. The structure consists of red Navajo Sandstone and has the shape of a broad, flat opening that frames the canyon system below.

The arch formed over millions of years through water erosion of Navajo Sandstone, gradually shaping the natural opening. This geological process is the same force that carved deep canyons and other rock formations throughout the region.

Photographers gather at Mesa Arch during sunrise hours to capture the morning light illuminating the red sandstone and reflecting on the underside. This effect has made the location a popular gathering spot for people seeking to capture the landscape's beauty in images.

A half-mile hiking trail from the park road leads to the arch with interpretive signs along the way. The path is well-maintained and relatively flat, making it accessible for most visitors.

The arch's distinctive form resulted from a pothole process, where water seeped into small depressions and gradually carved them into larger cavities. This creation method sets Mesa Arch apart from many other arches in the region.
