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...

A second, less extensive event, is recorded by deposits of both the inland ice cap and cirque glaciers. Between these two glacial events, a higher stand of sea level produced beaches and terraces at 10.6 m to 12 m above the present sea level.
