Name

The Ārai Terraces were so named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE; 1959–60) because they are a natural barrier to sledge travel which the party was unable to traverse, ārai being the Māori term for barrier.^[1]

Location

Peletier Plateau in southwest of map

The Ārai Terraces are in the eastern Queen Elizabeth Range to the northeast of the Prince Andrew Plateau, east of the Moore Mountains and Mount Rabot. The Linehan Glacier and Lowery Glacier define the western boundary, and the Robb Glacier the eastern boundary. Features around the Ārai Terraces include Bengaard Peak to the south, Softbed Ridges, Fazekas Hills and Mount Oona to the north.^[2]
