NABSQNO 12S-634670-4000920. This unnamed caprock natural arch has eroded through the top edge of a projecting wall of DeChelly sandstone known as Blade Rock. The lintel of the arch is a harder layer of the DeChelly member that formed over softer layers of the same member. It is located in Canyon DeChelly National Monument, about 3 miles east of Chinle, Apache County, Arizona. The services of a guide must be used to visit this arch. It is not visible from any rim overlook. Vreeland listed this arch as number 11-16 in his catalog. It has a span of about 20 feet.
