Abstract
Lake Ontario (74 m above sea level) is located 150–250 km north of the Late Wisconsinan southern limit of the Laurentide Ice Sheet in North America (Figure 1). Multibeam bathymetric mapping in deep eastern Lake Ontario (Figures 2, 3) revealed a set of parallel, straight, narrow ridges trending 235±5° which commonly rise 10–20 m above the surrounding lakefloor. The mapped ridges range in length to 6 km and from 60 to 600 m in width.
