Site details

Historic passenger-cargo steamer wreck off Point Bennett, San Miguel Island. NOAA/NPS and NOAA-authored dive writing confirm underwater remnants and diver interest, with machinery and organized wreckage remaining in a swell-exposed sanctuary setting. This should be treated as a cold-water boat wreck for capable divers, not a casual shore site.
