Observations on the Glacial History of Livingston Island

Livingston Island, one of the South Shetland Islands, Antarctica, has recorded at least three glacial events. During the oldest event, all areas of the island below 200 m were covered by an expanded island ice cap. At that time Livingston Island ice probably joined that of adjacent islands. A second...
