drumlin
Ice-sculpted ridge
A drumlin is an elongated, oval-shaped hill formed by glacial activity, with its long axis parallel to the direction of ice flow.
Drumlins typically have a steeper slope on the side that faced the advancing glacier and a gentler slope on the lee side.
They often appear in groups called drumlin fields: The landscape of central New York is dotted with drumlins.
