Anomalous Erosional Topography in Victoria Land, Antarctica

Abstract

An area of some 18 square kilometers at the head of Wright Dry Valley displays an erosional terrain of unique characteristics—a labyrinthine complex of erratic, interconnecting channels cut to depths of more than 100 meters in bedrock. It is interpreted as a result of catastrophic fluvial erosion, probably analogous to that which produced the Channeled Scabland of eastern Washington, though on a greatly reduced areal scale.
