Recharted in 1930 by DI personnel on the "Discovery II" and named for Sir Samuel H. Wilson, Permanent Under-Secretary of State for the British Colonies. Wilson Rock is the middle rock of a chain of rocks extending WSW from Turmoil Point, the westernmost point of Bristol Island. These are Grindle Rock, Wilson Rock and Freezland Rock. Wilson
