Wright Upper Glacier

Wright Upper Glacier (77°32′S 160°35′E) is an ice apron at the upper west end of Wright Valley in Asgard Range, Antarctica. It is formed by a glacier flowing east from the inland ice plateau. Named by the Victoria University of Wellington Antarctic Expedition (VUWAE) (1958–59) for C.S. Wright, a member of the British Antarctic Expedition (1910–13), after whom the "Wright Glacier" (adjusted to Wright Lower Glacier by the VUWAE) was named.[1]

Wright Upper Glacier viewed from the air. Airdevronsix icefalls visible at head of glacier. Labyrinth is in the foreground.

Two massive icefalls descend from the Wright Upper Glacier into the Wright Valley, the 5 km (3.1 mi) wide and 400 m (1,300 ft) tall Airdevronsix Icefalls and the equally tall 0.92 km (0.57 mi) wide Warren Icefalls, which was named by the Advisory Committee on Antarctic Names (US-ACAN) in 2004 for Alden Warren, a longtime photographer (scientific and technical) with the United States Geological Survey, involved in documenting maps of Antarctica.[2][3]

Vortex Col is a col leading from the plateau into the south side of the glacier. At this locality, winds carrying clouds of snow from the polar plateau are deflected by Mount Fleming and funneled down this depression. The descriptive name was given by New Zealand Antarctic Place-Names Committee (NZ-APC).[4]
