Drumlin

Common card · No. 201076

A drumlin 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 name is derived from the Irish word droimnín ("little ridge"), first recorded in 1833. Assemblages of drumlins are referred to as fields or swarms; they can create a landscape which is often described as having a 'basket of eggs topography'.
