Drumlin Drumlin A drumlin, from the Irish word "droimnín" ("littlest ridge"), first recorded in 1833, and in the classical sense is an elongated hill in the shape of an inverted spoon or half-buried egg formed by glacial ice acting on underlying unconsolidated till or ground moraine. Drumlins occur in various shapes and sizes, including symmetrical (about the long axis), spindle, parabolic forms, together with transverse asymmetrical forms; their long axis is parallel to the direction of movement of the formative flow at the time of formation. Drumlins are typically long, less than high and between wide. Drumlins generally have a length:width
Glacial series direction parallel to the edge of the ice mass and are a feature of Northern Central Europe. These valleys, created by glacial meltwaters, do not appear in the Alpine Foreland as they do, for example, in North Germany because their function was assumed by the great rivers that already existed in the region - the Danube, Rhine, Rhône and Po - or their tributaries, which transported away the meltwaters of the glaciers. The Scandinavian ice sheet reached or crossed Northern Central Europe several times. The landforms of the glacial series here thus follow one another from north to south: The
