View of the Victoria Land coast off Cape Roberts during Oligocene and early Miocene times (from Barrett, 2007^[1]). (A) Glacial period, with an expanded inland ice sheet feeding thin temperate piedmont glaciers depositing sediment to a shallow shelf to be reworked by waves and currents nearshore with mud settling out offshore. (B) Interglacial period, with higher sea level and a much reduced ice sheet. Sediment carried to the coast largely by proglacial rivers. Low woodland beech forest at lower elevations. Insets for A and B show examples of the modelled extent of an ice sheet that might have existed during glacial and interglacial periods in early Oligocene times, representing 21 × 106 km3 of ice (50 m of sea level equivalent) in A, and 10 × 106 km3 of ice (24 m of sea level equivalent) in B (DeConto et al., 2007^[2]). The location of Cape Roberts is shown as a white filled circle. TAM = Transantarctic Mountains, EAIS = East Antarctic Ice Sheet.
