At the surface, the entire region is "Moraine terrain", with the glacial landforms of moraines, drumlins, eskers, kames, outwash plains and till plains, all relics from recent glaciation. In the multitude of glacier-formed depressions are wetlands and many of the state's "10,000 lakes", which make the area prime vacation territory.
