HOUGHTON - National Park Service officials said Monday a 55-year-old Minnesota man died Saturday while scuba diving off the north shore of Isle Royale National Park.
Lloyd Krohn, 55, of Wyoming, Minn., was diving in a party of three on a charter scuba dive to the shipwreck of the Kamloops, a 250-foot Canadian freighter that sank in 1927 and lies at a depth below 200 feet.
At about 11 a.m. Saturday, Krohn's two companion divers noticed he was having an unknown difficulty. They attempted to help him, but were forced to send him to the surface of the water alone after he became unconscious, park staff said in a news release.
Krohn was spotted by the charter boat crew and brought aboard unresponsive and not breathing. Ranger emergency medical technicians who responded to a distress call declared Krohn dead at the scene.
The Keweenaw County Medical Examiner is working with park rangers to determine a cause of death and further investigate the circumstances of the fatality.
Isle Royale National Park Superintendent Phyllis Green has temporarily closed the Kamloops shipwreck to diving. The wreck, which is located about 300 feet of the north shore of Isle Royale, is considered an expert dive due to the depths involved.
"We are deeply saddened by this scuba accident," Green said. "Divers understand the risks involved in diving at such extreme depths, but accidents can happen. We will do a thorough examination of the accident and review operations at the site before opening it to further recreational diving."
