A new island suddenly emerged from the sea just off the coast of North Carolina — but officials warn that the spit of land is too dangerous for humans to explore. The new sandbar island seemingly sprang from the ocean in just a few weeks, the Virginian Pilot reported. The island, which is about 1 mile (1.6 kilometers) long and about 480 feet (146 meters) wide, lies off the coast of Buxton, North Carolina, which is part of the Cape Hatteras National Seashore.
