The Echelmeyer Ice Stream, formerly known as Ice Stream F, is a glaciological feature of the West Antarctic Ice Sheet. It is an ice stream flowing west to the Shirase Coast to the north of the MacAyeal Ice Stream, and is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983–84 and originally named Ice Stream A, B, C, etc., according to their position from south to north.
