Abstract:Glacial geologic mapping conducted during the 1974-75 field season revealed that at least two glacial events have affected the upper Rennick Glacier region: an older Evans glaciation probably correlative with a major expansion of the east antarctic ice sheet, and the Rennick glaciation, which since the end of the late Wisconsin has been in a retreat phase. During the 1980-81 and 1981-82 field seasons sites were visited to document the physically and climatically induced changes characteristic of the retreat phase of the Rennick glaciation. Preliminary results indicate that the upper Rennick Glacier area is characterized by glaciodepositional and glacioerosional features characteristic of wet-based ice, surface-water flow, and ablation values far more intense than in more southerly areas of the Transantarctic Mountains, and by marked thinning of ice in Evans Neve.
