Abstract
This map show the distribution and thickness of the principal clay unit. The clay unit consists of a thick, massive bed of relatively pure clay in some areas; in other areas it consists of discrete layers of clay alternating with layers of silt and very fine sand (varved clay). The upper layers of the clay unit commonly grade into a layer of silt and very fine sand. Small, isolated clay deposits not associated with the principal clay unit are not mapped.
