Santa Rosa, New Mexico. In March 1976 two student divers left an open-water class at the Blue Hole and swam into the cave at the bottom of it. The search for them took six weeks and nearly killed a police diver, and the city sealed the cave with a steel grate. Forty years later a survey team opened it, mapped it to 194 feet, and lost one of its own. Told from the published record.

Near Mount Gambier, South Australia, 28 May 1973. Eight divers descend through a three-foot hole in a paddock into one of the largest flooded chambers in the country, with no guide line and no dive plan. At about 180 feet, four of them keep going. It takes more than ten months to bring the last of them back, and the accident changes cave diving in Australia. Told from the published record.

Plurdalen, Norway, 6 February 2014. Five Finnish divers set out to swim through a flooded cave under a mountain to a dry chamber on the other side. Two die at about 370 feet, one of them stuck in the narrowest part of the passage. The authorities call the recovery too dangerous. Six weeks later the survivors and their friends go back in themselves. Told from VG's reconstruction, Yle and the Finnish Divers' Federation report.

Wimberley, Texas, 26 February 1984.

Two come back up. Told from the diver's own accident report and a local diver's account, both reprinted by the NSS Cave Diving Section in 1984.
