mountain range of Antarctica, located in Ross Dependency (New Zealand) along the western edge of the Ross Ice Shelf. The range reaches an elevation of 14,856 feet (4,528 m) in Mount Kirkpatrick. The mountain range rises between the Dry Valleys and Queen Maud Range of the Antarctic Mountains and is separated from the latter by the Beardmore Glacier. The range has areas of peneplain, created by past erosion, before it descends to sea level. Mount Falla, capped by 14 flat-lying lava flows of basaltic composition, is located in the range. The range was discovered by the British explorer Ernest H. Shackleton in 1908 and named for Queen Alexandra of England.
