Another striking feature of Ship Rock are the dikes, or wall-like sheets of lava that radiate away from the central neck. These dikes would have been intruded at some depth below the earth's surface at the time that the Ship Rock eruption was occurring. Like the neck, the dikes have since been exposed due to differential weathering through time of the hard lava of the dikes, and the more easily eroded sandstone and shale of the countryrocks.
