大湖盆地-
五大湖盆地都是冰挖掘出来的，如今许多现有地形都是这种大陆冰川作用的结果。高山山谷里有着冰川的遗迹。在冰川的下游，有一些冰川形成的清澈而冰冷的湖泊。
The Great Lakes basins were excavated by the ice , and many present landforms are the result of this continental glaciation . In the high valleys , there are remains of glaciers , while below them are clear , icy lakes which the glaciers made .
