The Great Lakes are the result of glacial scour and pooling of meltwater at the rim of the receding ice.

Examples of depressions created by glacial scour include Deep Lake and Wolf Swamp just west of Big Pocono State Park.

The stream's valley, which runs north-to-south ( parallel to the glaciers during the Ice Age ), has been significantly deepened by glacial scour.

The Glacier Movements also created other distinctive features of this region, including peat bogs and swamps, which resulted when glacial scour produced un-drained scars on the plateau's surface.
