has been analysed in a conceptual framework embracing recent advances in ice-sheet
dynamics, particularly with regard to basal thermal zonation, subglacial hydrology, evidence
for fast ice flow (palaeo-ice streams), and an appreciation of the length of time represented
by the glacial landform record. We refer to this conceptual framework as the process of
inversion (Kleman & Borgström, 1996), ie extraction of icesheet properties from glacial …
