...James D. Carl Abstract A belt of oriented till ridges along the southern margin of the St. Lawrence Valley, New York, is shown to be similar in form and occurrence to Swedish Rogen moraine, Canadian ribbed moraine, and Finnish hummocky active ice moraine. It is the first such occurrence described...
