They are formed by streams that deposited minerals that flowed on top of glaciers, inside the cracks of glaciers, and in tunnels below glaciers
Eskers are long ridges of gravel or sand deposited by a stream that flows in a tunnel under a melting glacier.
Drumlins and eskers are found in glacial areas. Drumlins are hills made of glacial sediment and till, while eskers are long ridges of glacial drift.
