The easternmost extremity of the ice cap that developed in the Tasmanian Central
Highlands during the time of most extensive Late Cainozoic glaciation lay on the doleritecapped
Central Plateau east and north-east of Lake St Clair. During the Last Glacial
Maximum (LGM), the more restricted ice cover included a small discrete ice cap (probably less
than 250± 300 m thick) that formed on the Central Plateau. The LGM ice limits on the
southern part of the Central Plateau, including all five southern outlet valleys, are reported
here. Earlier ice limits have been identifed in two of these valleys, but on the plateau proper
earlier glacial deposits have been generally extensively reworked beyond the LGM limit, such
that confirmation of a glacial origin for diamictons on slopes is difficult. South of the plateau,
the oldest deposits fooring lower reaches of two outlet valleys indicate that ice flowed
southwards directly from the plateau, but later deposits indicate diffluent flow from the Derwent
