   a remarkable headland of columnar basaltic rock in North Ireland, projecting into the North Channel from the Antrim coast at Bengore Head, 7 m. NE. of Portrush; is an unequal surface 300 yds. long and 30 ft. wide, formed by the tops of the 40,000 closely packed, vertical columns which rise to a height of 400 ft.
