Excerpt from 50th Annual Report of the Regents, 1896, Vol. 2: Report of State Geologist and Field Assistants Outside of the sand-covered areas the surface drift is largely morainic in character. In many places heavy moraines lie in proximity to, or banked up against the out-lying gneiss ridges. Surface boulders are numerous over most of the district, and their extremely local character is worthy of remark and is most strikingly shown along the line of contact between the Potsdam sand stone and the Calciferous.
