Lake Iroquois - Watertown phase
The ice mass begins to migrate north, away from the western tip of lake Ontario, creating the early stages of glacial Lake Iroquois. The lake drained eastward into the mohawk valley, near Rome New York. To the east a small glacial lake (Glenfield) was created, which drained into the larger water body of Lake Iroquois. The ice was indirect contact with the lake, creating a calving ice margin, which deposited several sub aqueous outwash fans of rhythmically bedded silts and clays.
