Clear water briefly reveals decades-hidden Lake Superior tugboat

A rare view, not a new discovery

A stretch of unusually clear water gave Camp Amnicon director Hannah Damon and her 9-year-old son a rare look at the submerged remains of the A.H. Pitz, a wooden tugboat off Wisconsin’s Lake Superior shore. The wreck was already known; the new moment was being able to make it out beneath the water. ^{[1] [2] [3]}

The vessel is listed in the Wisconsin Shipwrecks database maintained by Wisconsin Sea Grant and the Wisconsin Historical Society. Its record says the tug was built in Manitowoc in 1923, measured nearly 70 feet long and was abandoned at the Amnicon River mouth in 1951. ^[1]

Visibility changed within a day

The visibility appears to have been temporary, not the result of a newly exposed ship rising above the lake. Damon recalled seeing beams, cables and brackets while swimming with her son. Maritime archaeologist Tamara Thomsen told Northern News Now that the last documented above-water sighting was in 2001. ^{[2] [3]}

Damon said the lake looked calm again the next day, but the water had turned murky. Camp Amnicon shared footage of the sighting, and local coverage said community members responded with memories of seeing the tug decades ago. ^{[2] [3] [4]}

The Wisconsin Shipwrecks record marks the site as eligible for the National Register; it does not say the vessel was newly excavated or recovered. Northern News Now reported that removing artifacts or otherwise disturbing the wreck is illegal, so the archaeological advice is to observe rather than touch. ^{[1] [2]}

Changes in water level, wind and suspended sediment can alter what visitors can see without moving the wreck itself. That makes the brief sighting newsworthy as a window onto local maritime history, while the registry provides the longer record of the tug’s identity, age and resting place. ^{[1] [2]}
