Site details

On 21 July 1948 a U.S. Air Force B-29 Superfortress on a classified atmospheric-research flight skipped off the surface of Lake Mead and sank largely intact in the Overton Arm. The aircraft now rests in roughly 95-125 feet of fresh water (varying with lake level) and is one of the most famous inland wreck dives in the United States. The National Park Service protects the site: it may be dived only on guided, no-touch trips with the permitted operator, two divers per guide, with technical decompression certification required.
