Example Fin Natural Arch

NABSQNO 12S-576782-4085460. Full Moon Arch is a fin natural arch eroded through DeChelly sandstone. The opening is an upright oval aperture and is the basis for the arch's name. The opening is almost certainly due to differential erosion in the same member as a result of an area of relatively weak cementing.

Full Moon Arch is in the Mystery Valley area of Monument Valley in northern Arizona. Since this is a Navajo Tribal Park, the services of a guide must be obtained to visit the arch.
