Geometric and cross-cutting relationships between the Wilson Piedmont Glacier and raised beach ridges indicate that the glacier margin has undergone Holocene ‘ uctuations. During mid-Holocene time, the Wilson Piedmont Glacier retreated to a position less extensive than at present. A subsequent readvance culmi nated less than 250 years ago. Since ad 1956, the glacier and adjacent large snow ramps have retreated up to 600 m in some locations. Large snowbanks have also disappeared. Although the cross-cutting relationships and chronology indicate a late-Holocene advance at approximately the same time as the ‘Little Ice Age’ event, the magnitude and style of that advance differ from those of the classic ‘Little Ice Age’ glacier ‘ uctuations in the Northern Hemisphere.

Key Words: Antarctica • Wilson Piedmont Glacier • raised beaches • ‘Little Ice Age’ • Holocene
