Drumlins
A low oval mound or small hill, typically one of a group, consisting of compacted boulder clay molded by past glacial action.
Drumlins are commonly found in clusters numbering in the thousands. Often arranged in belts, drumlins disrupt drainage, so that small lakes and swamps may form between them. Large drumlin fields are located in central Wisconsin and central New York; in Northwestern Canada; in Southwestern Nova Scotia and in Ireland.
Drumlins are generally found in broad lowland regions, with the long axis roughly parallel to the path of glacial flow. Although they come in a variety of shapes, the glacier side is always high and steep, while the lee side is smooth and tapers gently in the direction of ice movement. Drumlins can vary widely in size, with lengths from 1 to 2 km. (0.6 to 1.2 miles), heights from 15 to 30 m. (50 to 100 ft.) and widths from 400 to 600 meters.
Most drumlins are composed of till, but they may vary greatly in their composition. Some contain significant amounts of gravels, whereas others are made up of rocks underlying the surface till. (Rock drumlins)
