Abstract

Some of the larger valleys of pre-glacial and inter-glacial topography have been located and described by Dr. S. W. Beyer and by Prof. I. A. Williams in earlier papers. Further information concerning these and other features is afforded by a study of the shallow artesian wells of the county and by a careful examination of the major features of the present surface several of which are hills, ridges and valleys of pre-Wisconsin time modified by a mantle of glacial till.
