Drumlins

• Drumlins are elongated, oval shaped hills made up of unsorted glacial deposits, comprising till,
• Drumlins are formed as the glacier becomes overloaded with sediment and deposits it, streamlining the sediment as it flows over it.
• The steep ‘stoss’ slope faces up-valley and the more gently-sloping ‘lee’ slope faces down-valley.
• Drumlins are found in groups, with the tapered end of each hill pointing in the direction of glacier flow – these swarms are sometimes likened to a ‘basket of eggs’.
• Drumlins occur widely within the moulded and streamlined scenery of the central lowlands of Scotland.
• Each drumlin is a small hill, tending towards an egg shape, with its steepest slopes and summit at the up-ice end.
• Although they come in a variety of shapes, the glacier side of a drumlin is always high and steep, while the lee side is smooth and tapers gently in the direction of ice movement.
