Exploration and name

edit

The Prince Andrew Plateau was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1961-62) for Prince Andrew, son of Queen Elizabeth II of Great Britain.

Location

edit

The Prince Andrew Plateau is in the southern Queen Elizabeth Range between the Moore Mountains and Ārai Terraces to the north and the Peletier Plateau to the south. The Marsh Glacier is to the west and the Bowden Névé to the east.[2] Features to the east include Painted Cliffs in the southeast, which include Dawson Peak and Mount Picciotto and the Disch Promontary further north. Features to the west include Dakota Pass in the south, Cranfield Peak, Mount Weeks and New Year Pass to the south of the Moore Mountains. Features to the north include Helm Glacier, Linehan Glacier, Turnabout Ridge, January Col, Claydon Peak and Baulch Peak.[2]

Turnabout Ridge

edit

83°18′S 162°35′E / 83.300°S 162.583°E / -83.300; 162.583. A high, rugged ridge, 10 nautical miles (19 km; 12 mi) long, lying between Linehan Glacier and Lowery Glacier.
