Title
Lake Iroquois
Description
This map shows the approximate outline of a proglacial lake dating some 13,000 years ago, when the Laurentide ice sheet was in retreat and blocked water from flowing north into the North Atlantic Ocean. Instead, its outlet was diverted through present-day Rome and down the Hudson River. We see here the roughly similar footprints of Lakes Iroquois and the later Ontario, with another important difference being a ridge of gravel deposits resulting from the earlier lake. In Western New York, the ridge road was an important trail; modern-day SR 104 follows the same route.
