Site details

The Kamloops, a Canada Steamship Lines package freighter, vanished with all 22 hands in a December 1927 storm and was not found until 1977, lying on her starboard side off Twelve O'Clock Point in roughly 175 to 260+ ft of near-freezing water. She is astonishingly intact and undisturbed — cargo still in her holds and crew remains aboard, including the well-preserved body divers call 'Grandpa' in the engine room — making her both Isle Royale's ultimate technical dive and a de facto gravesite that must be treated with respect. Only fully qualified trimix/CCR divers on expedition charters should attempt her, and several divers have died here.

boatwreck

Extreme depth (175-260+ ft) — full trimix/CCR decompression dive only; multiple diver fatalities have occurred here

Human remains of the 1927 crew are still inside the wreck — treat the site as a gravesite; engine-room penetration is strongly discouraged and disturbance is prohibited by federal law

Water near 1-3 C at depth; severe cold stress and DCS risk

Wreck lies on its starboard side on a steep slope — easy to exceed planned depth

Extreme remoteness — nearest recompression chambers in Minneapolis and Milwaukee
