Swithinbank Range (81°42′S 159°0′E / 81.700°S 159.000°E / -81.700; 159.000) is a small range from the Churchill Mountains,

Location

The Swithinbank Range extends eastward between Donnally and Ahern Glaciers to the west side of Starshot Glacier.[1] It faces the Surveyors Range on the east side of the Starshot Glacier.[2] It was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1959–60) for Charles W. Swithinbank, glaciologist that season at Little America V.[1]

Geology

The bulk of the Holyoake and Swithinbank Ranges are made up of the Shackleton Limestone formation, which lies unconformably on an unweathered surface cut across beds of the Goldie Formation north of the Nimrod Glacier. It includes the Cambrian limestone that crops out between the Byrd and Nimrod Glaciers and in the upper Beardmore Glacier.[3]
