Abstract

The AA. hypothesize that 1) many of the subhorizontally stratified deposits represent full-glacial eolian sand sheets, formed when sand supply was limited by seasonally variable combinations of ice cementation, snow cover, high groundwater tables, and vegetation, and 2) many surface dunes reflect late-glacial and postglacial reworking under conditions of increased short-term availability of loose sand. The morphology of some surface dunes may therefore reflect mainly the intensity of reworking since the last glacial maximum, rather than full-glacial paleowind vectors or the age of the bulk of the underlying deposits
