Location

edit

The Lowery Glacier flows north from Prince Andrew Plateau, Antarctica, along the east side of the Queen Elizabeth Range to enter Nimrod Glacier.[1] To the north of Softbed Ridges it converges with Robb Glacier, but the two glaciers separate when they reach Taylor Hills.[2]

It was named by the New Zealand Geological and Topographical Survey Expedition (1959–60) for J.H. Lowery who, as a member of a field party, suffered injuries when a Sno-cat broke through a crevasse bridge off Cape Selborne in November 1959.[1]

Icefalls

Arai Terraces

edit

83°12′S 163°36′E / 83.200°S 163.600°E / -83.200; 163.600. A series of crevassed terraces and icefalls close southward of Fazekas Hills, near the head of Lowery Glacier. So named by the NZGSAE (1959-60) because the feature is a natural barrier to sledge travel which the party was unable to traverse. Arai is the Maori term for barrier.[3]
