Champlain Sea


Extensive but discontinuous shore features, mainly beach ridges, on the south side of the basin, and terraced glacial and proglacial deltas on the north side show that the present altitude of the highest marine submergence is about 650–750 feet (198-228 mtrs) in the north and 450–525 feet (137- 160mtrs) in the south. It has not yet been possible to trace very far the strandlines of individual water planes except in the Champlain valley.[1]
