Cleft Ledge

Cleft Ledge (-77.53333°N, 160.88333°W) is a flat-topped ridge 1 nmi long and 0.3 nmi wide between Shaw Trough and Healy Trough in the Labyrinth of Wright Valley, McMurdo Dry Valleys. The ledge rises to 920 m and is 0.3 nautical miles northwest of Hoffman Ledge. The name is descriptive and was recommended by the Advisory Committee on Antarctic Names (2004) because a central north-south hanging valley nearly divides the ledge in half.
