CAPE POINT (AP) — Cape Hatteras National Seashore on North Carolina’s Outer Banks asked the public this week to help clean up a shipwreck that spread debris across a mile of beach at Cape Point.

The Charlotte Observer reports a shrimp trawler flipped over and broke apart near the beach early Monday, leaving the sand covered in wood, nails and ship fragments.

A park statement says the ship’s three crew members were found alive and taken to hospitals for medical evaluations. The cause of the wreck is under investigation.

The debris closed a section of beach between off-road vehicle ramps 48 and 49, and volunteers helped to clear the wreckage Tuesday afternoon. The park’s website says the ramps were open to off-road vehicles as of Tuesday night, though drivers should look out for debris.
