The gravels related to the Iowan glaciation of northeastern Iowa have been studied in the field and laboratory. Three factors were significant in the field correlation, (a) stratigraphic relations (b) topographic position and (c) amount of weathering. In the laboratory the size, range, shapes, and lithology of the gravels were studied but little of value for correlation purposes was obtained.
