Spillway Icefall (85°1′S 166°22′W) is a spectacular icefall descending northward through central Duncan Mountains to Amundsen Coast. The icefall cascades through the mountains giving the appearance of a turbulent spillway on a dam. The descriptive name was approved by Advisory Committee on Antarctic Names (US-ACAN) from a proposal by Edmund Stump, geologist, Arizona State University, who worked in this area, 1974-75.
