Cleft Ledge


Cleft Ledge is a flat-topped ridge long and wide between Shaw Trough and Healy Trough in the Labyrinth of Wright Valley, McMurdo Dry Valleys. The ledge rises to and is 0.3 nautical miles northwest of Hoffman Ledge. The name is descriptive and was recommended by the Advisory Committee on Antarctic Names because a central north-south hanging valley nearly divides the ledge in half.
