When the Florida Keys National Marine Sanctuary created its Shipwreck Trail, it established an underwater guide for the public to uncover stories behind nine vessels whose remains rest beneath the waves. These sites invite visitors to explore the maritime history of the national marine sanctuary by providing access to unique and fragile archaeological resources. Unfortunately, looters have recently plundered one wreck resting in shallow water off Marathon for almost 190 years.
“The North America lies in a very accessible location in water no deeper than 14 feet,” said sanctuary maritime archaeologist Matthew Lawrence. “In 2021, we started to see that someone was moving ballast stones and exposing (the) wooden hull. The disturbance has continued since then. They were probably looking for a souvenir, like a nail, but the exposed wooden hull will now degrade even faster.”
Lawrence elevated his concern at a recent meeting of the Sanctuary Advisory Council, explaining that what some might believe to be an innocuous activity, like taking a small memento from their visit, may cause long-term damage and prevent others from enjoying the site.

The North America rests in the sand and grass flats north of Delta Shoal, just east of Sombrero light. The vessel was lost in 1842 while carrying dry goods and furniture. Florida Keys wreckers saved the cargo, but not the ship.
“Shipwrecks provide unique information about our past that’s not in the written record,” explained Lawrence. “They provide exciting opportunities for recreational and educational experiences that are non-consumptive, as long as visitors respect the history. We have a saying: Take only pictures; leave only bubbles.”
Historical resources, such as shipwrecks and archaeological sites, within the sanctuary are protected by both federal and state laws, but they remain open to the public for diving and snorkeling. Lawrence urged the council to educate their constituencies about regulations that govern historical resources, asking for help in keeping an eye on boats visiting shipwreck sites.
