Glacial history of the upper Derwent Valley, Tasmania.
Part of an extensive ice cap that developed in the Tasmanian Central Highlands during the late Cenozoic discharged southwards via a major outlet glacier that occupied the valley of the Derwent River. At least three and probably five phases of glaciation took place. The first and most extensive glaci...
