Pitkevitch Glacier

(Redirected from DuBridge Range)

Pitkevitch Glacier (71°23′S 168°52′E / 71.383°S 168.867°E / -71.383; 168.867 (Pitkevitch Glacier)) is a glacier, 20 nautical miles (37 km; 23 mi) long, flowing north from the Admiralty Mountains along the west side of DuBridge Range in Antarctica. The glacier reaches the sea just east of Atkinson Cliffs, where it forms Anderson Icefalls. A portion of the terminus merges northwestward with Fendley Glacier.[1]

Exploration and naming

edit

The Pitkevitch Glacier was mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960–63. It was named by United States Advisory Committee on Antarctic Names (US-ACAN) for Staff Sergeant Leonard M. Pitkevitch, United States Air Force (USAF), who perished in the crash of a C-124 Globemaster aircraft in this vicinity in 1958.[1]

Location

edit

The Pitkevitch Glacier forms in the Admiralty Mountains to the south of Brewer Peak, and flows northeast along the west side of the DuBridge Range, which includes Mount Emerson and Mount Locke. The Shipley Glacier flow along the east side of the DuBridge Range The Pitkevitch Glacier flows past Crandall Peak to its west. At the Atkinson Cliffs some of its ice splits off to join the Fendley Glacier while the remainder descends through the Anderson Icefalls to the Pacific Ocean on the north coast of Victoria Land. [2]
