Station 10: Drumlin
Edmund Hill is a drumlin, an elongate hill formed by glacial action. The long axis is typically in the direction of glacial flow during the last Ice Age. Geologists have found that many drumlins have a core of glacial till left by glaciers that predate the last one. Drumlins are common in eastern Massachusetts. Examples in Northborough include Assabet Hill and Cedar Hill.
