NABSQNO 12S-406355-4079165. This very unusual double irregular natural arch has eroded through an iron concretion emerging from Navajo sandstone. It is located near the western edge of the Paria Plateau and east of House Rock Road, in Coconino County, Arizona. Vreeland listed this arch as number 12-9 in his catalog and reported a span of 6 feet for the larger opening.
