| Description/Notes | Image Description from historic lecture booklet: "When the glacier had melted off in the vicinity of the present Chicago and Detroit two points north of the divide, the eastern region about the Mohawk and St. Lawrence valleys, was still full of ice. It will readily be seen, therefore, that there were lakes gathered on the north. As the ice melted farther back these lakes became greater in size and often changed much in form. But in time the ice melted out of the Mohawk Valley in New York and the drainage of these glacial Great Lakes poured out between the Adirondacks and Catskills to the Hudson and the sea. Still later, the glacier melted out of the St. Lawrence Valley, and the Great Lakes came to their present levels and forms. |
