The purpose of this paper is to discuss and evaluate various alternative hypotheses concerning the evolution of the level interfluvial divides on the Kansan Till plain in southern Iowa and northern Missouri. About four-fifths of the plain is dissected (3), but the undissected remnants have an almost flat surface. In contrast to this the undissected portion of the much younger surfaces of the Mankato and Cary till plains have an undulating topography with numerous closed depressions and isolated low knolls.
