Although deposits that indicate two or more advances of Pleistocene continental glaciers across New York State have been found at Toronto, Ontario, and in northern New Jersey and southeastern New York, there is no record of the discovery of similar deposits in central New York that are conclusive evidence of the existence of an interglacial period between an inferred early ice invasion and the formation of the deposits assigned to the Wisconsin stage. Several observers have described occurrences that are interpreted as evidence of multiple glaciation, but these occurrences appear to be inadequate to afford a solution of the problem, or the record of them involves misapprehensions as to the nature of the material considered. Although the deposit to be described below is interpreted as evidence of multiple glaciation, the interpretation would be greatly strengthened if other deposits should be discovered that appear to be of the same nature . . .
