NABSQNO 15S-538741-3993963. This unnamed cave natural arch is one of several attractions of the Buffalo Point area in the Buffalo National River complex. Labeled as "small cave" on the maps of the Indian Rockhouse trail, it has a span of about 15 feet. The cave and arch have formed in Ordovician limestone, possibly the Plattin formation. Access is via a well maintained loop trail that is about 4 miles long.
