Ethel Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Ethel Rock offers some of Alaska's richest wreck diving. Water ranges 5-15°C, warmest July, August, September.
Ethel Rock offers a rugged Alaska dive, focusing on the fascinating local cold-water species. We often find spiny dogfish cruising by, and spotted ratfish are a frequent sight on the rocky bottom. Look closely for sidestriped shrimp and California spot prawns tucked into crevices. This site suits divers keen on observing specific Alaskan marine life, rather than extensive coral formations.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
Ethel Rock Wreck History
Year Sunk
1852
Vessel Type
passenger ship
Cause
collision
Long before the Titanic, the Great Lakes had their own tragic luxury liner disaster. The PS Atlantic was a grand paddle-wheel steamship, one of the finest of its day, carrying passengers and immigrants to new lives in the American Midwest. On a foggy August night in 1852, while traversing Lake Erie, the Atlantic was struck by the propeller-driven freighter Ogdensburg. The collision was catastrophic, and the Atlantic sank within minutes, taking an estimated 150 to 250 people with it, many of whom were Norwegian immigrants.
For over a century, the Atlantic was lost, becoming a ghost story of the Great Lakes. Rediscovered in 1991, the wreck is a stunningly preserved time capsule of the mid-19th century. Sitting upright in deep, cold water, its massive paddle wheels, engine components, and even luggage are still visible. This is a deep, advanced dive, but for those qualified, it offers a rare and haunting glimpse into a pivotal moment in maritime history.
