A geological aside

My upstairs neighbour is doing a doctorate in soil and geology and he went down into the construction pit and dug out some dirt. He found a bunch of shells. According to him, the Plateau was once the bottom of a giant lake (Lake Champlain?) about 10,000 years ago. When the waters settled, it left a layer of sand with these shells under it. Cool.
