It was discovered in 1841 during James Clark Ross`s expedition with HMS Erebus and HMS Terror, and was named after Francis Crozier, captain of HMS Terror. The extinct volcano Mount Terror, also named during the Ross expedition, rises sharply from the Cape to a height of 10,597 feet (3,230 m), and the edge of the Ross Ice Shelf (formerly known as the Barrier or Great Ice Barrier) stretches away to its east.
