The age and origin of the Labyrinth, western Dry Valleys, Antarctica: Evidence for extensive middle Miocene subglacial floods and freshwater discharge to the Southern Ocean

“Glacial curvilineations”: New glacial landforms produced by longitudinal vortices in subglacial meltwater flows

“…Furthermore, the anabranched tunnel channel pattern suggests initial contemporaneous erosion of most, if not all, tunnel channels (cf. Lewis et al, 2006) with progressive flow focusing and entrenchment. Lastly, GCL form a regionally continuous pattern spanning multiple anabranches, rather than localized groups confined to anabranched segments that would be expected if GCL formed time-transgressively.…”

Early to middle Miocene vegetation history of Antarctica supports eccentricity-paced warming intervals during the Antarctic icehouse phase

“…Ultimately, this led to the demise of most land plants in Antarctica,by ca. 13.85 Ma in the Dry Valleys (Lewis et al, 2006) and after ca. 12.8 Ma on the Antarctic Peninsula (Anderson et al, 2011).…”

Advances in permafrost and periglacial research in Antarctica: A review

“…They highlight the intriguing contradiction between the preserved volcanic ashes in their primary depositional locations covering regolith, stable over a long time period (6.4-11.3 Ma; e.g. Sugden et al, 1995;Marchant et al, 1996;Lewis et al, 2006), and the observed regolith transport.…”
