Example Buttress Natural ArchNABSQNO 12S-707387-3886322. Feather Rock Arch is a young buttress natural arch with an oval opening. It is considered young because there is a significant amount of rock in the lintel that does not participate in weight redistribution. It is eroded through a projecting wall of Zuni sandstone.
Feather Rock Arch, which has also been known as Pierced Rock, is on the Zuni Reservation, McKinley County, New Mexico. Although it can be easily viewed from state highway 53, a permit must be obtained from Zuni Tribal Headquarters before taking any photos. Vreeland included this arch in his catalog as number 17-5 and reported a span of 40 feet.
