A recent slump near the Genesee River in Livingston County, New York, exposed approximately 3 m of Wisconsinian varved strata containing numerous trace fossils in the silt layers, including Beaconichnus giganteum, Treptichnus, Cruziana, and Gordia, representative of the MermiaIchnofacies. This indicates a moderately firm substrate to preserve infaunal as well as epifaunal traces and colonization of the proglacial lake by arthropods. These are the first reported trace fossils in Pleistocene lake beds in New York and are similar to Pleistocene and Holocene trace fossils in glacial lake sediments reported from northern Europe and Ontario, Canada.

Additional authors: D. Jeffrey Over and Richard A. Young.
