Antarctic outlet glacier with a "sack-shape " source region of as yet not exactly known southward extent and area (approximately lO^km2). It has a uniform or slightly wavy longitudinal profile, an approximately 7 km wide calving front between 46°15 ' and 46°20'E, and a partly floating glacier tongue, extending to the seasonally changing front (classification 424 118 according to UNESCO-IAHS, 1970). The longitudinal mean surface slopes are 5-8 m km- on the tongue, 20-30 m km-1 in the step-shaped central section, and 8-12 m km-1 in the entrance region. The glacier is bordered to 15 km south of the front by about 500-m-wide serac belts, associated in some places with pressure ridges. It is distinctly separated from the continental ice sheet by three rock walls on the eastern edge. At the western edge the
