THE mystery of the Bermuda Triangle deepens as a mile-long island has risen from the sea but experts have warned to stay away.

The crescent-shaped island off the tip of Cape Point in Buxton, North Carolina, began surfacing in spring in the waters which surround the so-called Devil’s Triangle.

It has been dubbed Shelly Island by locals because of the vast quantities of shells which litter the shore, the Virginian-Pilot has reported.

The new island measures around one-mile long and more than 400 feet wide.

Visitor Janice Regan said she and her 11-year-old grandson christened the island and said it “was just a little bump in April”.

Janice and her grandson are not the only ones who have been exploring the surprise sandbar.

Anglers, seashell collectors, and photographers have all visited the island though it is dangerous to get to.

Dave Hallac, the superintendent of the Cape Hatteras National Seashore, which oversees Cape Point, has warned people should not attempt to try and walk or swim across a strong current which flows between the point and the new island.

Furthermore, Bill Smith, president of the North Carolina Beach Buggy Association, has said there could be even more hazards.

He said: “Sharks up to five feet long and stingrays as large as the hood of a truck have been spotted prowling beneath the surface.

“We’re worried about shark bites but we’re even more worried about drownings.”

The island popped up in the waters which surround the infamous Bermuda Triangle.

The Triangle lies in a section of the North Atlantic Ocean.

It covers an area of 440,000 miles of sea.

It’s one of the most heavily travelled shipping lanes in the world, with vessels crossing through to get to ports in America, Europe, and the Caribbean.

The Bermuda Triangle has also been blamed for the disappearance of dozens of planes and ships in the past 100 years.

On average, four aircraft and 20 yachts go missing every year.
