The Interpretation of a Tertiary Tillite at Mount Feather, Southern Victoria Land, Antarctica

Abstract
A Tertiary tillite occurs at an altitude of 2750 m on Mount Feather in southern Victoria Land. The tillite mantles a remnant of the floor of a south-east-trending glacial valley that pre-dates the cutting of the existing glacial drainage system in southern Victoria Land. Petrographic evidence suggests that ice which deposited the tillite drained a relatively distant source area.
