Surging of Fisher Glacier, Eastern Antarctica: Evidence From Geomorphology
Abstract A study of the geomorphology of the Prince Charles Mountains using colour vertical air photographs shows well–preserved old moraines throughout much of the outcrop area. Along Fisher Glacier, lower Lambert Glacier and the Amery Ice Shelf, within the altitude range 50–2 000 m, the old morain...
