When an ice age ended the land once covered by ice was mostly

It depends on the area. As the ice sheet moved backwards it meltedand water flowed from underneath it producing an ‘out wash plain’.In North American, these areas are seen as flat wide areas. The arealso called the Great Plains.

As they continued to move back and melt more, very large ice bergshaped pieces would break off the face (calving). The large icepieces would remain behind. The sheet would continue to move backand water containing sand, gravel and boulders would flow aroundthose ice bergs.

Many of these ice bergs would be so large that they formed largedeep lakes surrounded by moraines. These moraine would be filledwith that gravel, rocks and sand. The lakes are called kettles asthey remind people of very large cooking pots.

This area is very hilly with many lakes (large and small). Thereare still places where the moraines are removed and the sand andgravel is sold for building material like cement.

Further back, the mountains that were once there had been grounddown and that material became the sand, gravel and rocks. Themountains themselves were not like the Alps or the Rockies any morebut what we call the Appalachians.
