    1. Kettles-Potholes Presentation by Alex Palmer Geog.429

    2. Area Prairie potholes cover an area of 300,000 square miles . Reaching from the north central U.S to the south central of Canada.

    3. New Kettles When newly formed Kettles are cone shaped As time passes erosion takes place and modifies the shape of the kettle holes.

    4. Outwash surfaces Two glacial areas. Abandoned outwash surfaces. Ice left behind, or not. Formation of Kettles

    5. Melt out of ice Abandonment of outwash plain leads to one of two situations. No Kettle holes or, The production of Kettle holes depending on whether the ice melts out before or after the abandonment happens.

    6. Large amounts of ice. If there are large amounts of abandoned ice then the resulting landform is known as Kame and kettle topography.

    7. Hummocky Moraine Groups of steep sided hillocks. Glacial drift. Formed by dead ice wasting. Transverse to orientation of valley.

    8. Melt water factor. Sudden release of flood water can push large chuncks of glacial ice downstream.
