Drumlins
Drumlins are smooth, streamlined hills composed of glacial sediment, typically 15-40 m high and 300 m to 3 km long. They are aligned parallel to the direction of ice flow and are found in areas covered by large ice sheets.
Real World
The Ribble Valley drumlin field in Lancashire contains over 200 drumlins aligned northwest-southeast, revealing the direction of ice sheet flow during the last glacial period.
Exam Focus
State that the steeper stoss end faces up-ice and the tapered lee end points down-ice to show flow direction understanding.
