Legend has it that the ancestors of the ponies found on Ocracoke Island today came from shipwrecked vessels in the Graveyard of the Atlantic, or from Spanish explorers DeSoto or Cortez. Historians seem to think the ponies came with the Raleigh expeditions and were left on Roanoke Island. The current day ponies are fenced in and cared for by the National Park Service and can be seen grazing on the sparse grasses of the island.
