2021-01-17 Drumlin Farm. Drumlin farm is a farm in Lincoln, which is named for the large hill or drumlin it is built on. Drumlins, like the rest of the features in this project, are a direct cause of glacial retreat. This feature is formed when a retreating glacier bulldozes till into a small hill. Here we present a new geomorphological map of the active drumlin field and the forefield of Millajokull, a surgetype outlet glacier, Iceland. The map is based on aerial photographs taken in 1995 and LiDAR data recorded in 2008.

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.

The mapped landforms were initially identified on the Drumlins are elongated, aligned hills that form hidden from view beneath glaciers. The first modern drumlin field has recently been exposed by the retreat of Múlajökul. Previously this kind of landform could be studied only by focusing on drumlin fields that formed long ago in the Pleistocene, so this study provided a unique opportunity to understand drumlin formation better.
