title: Nebraskan and kansan stades: complexit and importance.
abstract: Several Early Pleistocene stadial tills and related soils in Kansas and Nebraska indicate a complex history of ice-sheet fluctuations. It is impossible to assign ages to individual till sheets solely on the basis of position in a stratigraphic column; all Early Pleistocene correlations must be reevaluated.
