  2. Moraine-dammed lake - Wikipedia

    en.wikipedia.org/wiki/Moraine-dammed_lake

    A moraine-dammed lake, occurs when the terminal moraine has prevented some meltwater from leaving the valley. When a glacier retreats, there is a space left over between the retreating glacier and the piece that stayed intact which holds leftover debris . Meltwater from both glaciers seep into this space creating a ribbon-shaped lake due to the ...

  3. Moraine - Wikipedia

    en.wikipedia.org/wiki/Moraine

    The medial moraine is the double line of debris running down the centre-line of the glacier. Lateral moraines can rise up to 140 meters (460 ft) over the valley floor, can be up to 3 kilometers (1.9 mi) long, and are steeper close to the glacier margin (up to 80 degrees) than further away (where slopes are typically 29 to 36 degrees).

  4. Proglacial lake - Wikipedia

    en.wikipedia.org/wiki/Proglacial_lake

    In geology, a proglacial lake is a lake formed either by the damming action of a moraine during the retreat of a melting glacier, a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic depression of the crust around the ice. [1]

  5. Washboard moraine - Wikipedia

    en.wikipedia.org/wiki/Washboard_moraine

    A washboard moraine, also known as minor or corrugated moraine, is a geomorphic feature caused by glaciers. The name "washboard moraine" refers to the fact that, from the air, it resembles a washboard .

  6. Tongue and groove - Wikipedia

    en.wikipedia.org/wiki/Tongue_and_groove

    Tongue and groove joints allow two flat pieces to be joined strongly together to make a single flat surface. Before plywood became common, tongue and groove boards were also used for sheathing buildings and to construct concrete formwork. A strong joint, the tongue and groove joint is widely used for re-entrant angles

  7. Kettle Moraine - Wikipedia

    en.wikipedia.org/wiki/Kettle_Moraine

    The major part of the Kettle Moraine area is considered interlobate moraine, though other types of moraine features, and other glacial features are common. [1] The moraine is dotted with kettles caused by buried glacial ice that calved off the terminus of a receding glacier and got entirely or partly buried in glacial sediment and subsequently ...

  8. Fort Wayne Moraine - Wikipedia

    en.wikipedia.org/wiki/Fort_Wayne_Moraine

    Moraines south of Lake Michigan and southwest of Lake Erie. A composite of three maps (Leverett 1915) (Leverett 1902) (Larsen 1986) and other sources. Colors represent moraines from the same time period of the Wisconsin Glacial epoch. The Fort Wayne Moraine is considered contemporary to the last stages of the Valparaiso Moraine.
