No direct evidence has been presented concerning the climatic conditions in central New York for most of the Wisconsin Stage. Evidence of patterned ground,very ften a result of ice wedgi g in areas of permafrost was reported from satellite photoimaging west of Cayuga Lake. This investigation was to confirm this observation and to further the conclusion that the patterned ground resulted from polygonal ice wedging. This investigation included topographic analysis, Ground penetrating radar, ground conductivity and soil coring. Topographic analysis showed that the polygons had centers raised up to 1 m, but the radar and conductivity results were inconclusive. Boring was inhibited by many large clasts but did show that the area where an ice wedge was suspected had finer grained soil, which suggested eolian filling of the wedge during warming and meltout. A recessional moraine bordering the study site was correlated with better dated moraines east of the lake and constrained the time of periglacial conditions in the study area from less than 16ka to 14.7ka ago.
