What are Eskers, Drumlins, and Moulins? Eskers - Ridge of till forming where a glacial meltwater tunnel once was, as the meltwater decreased as the glacier retreated the meltwater channel was unable to suspend the till and it gets deposited. Drumlins - Till deposits with a steep, wide upglacial side and a shallower thinner downglacial side.

Eskers are the sinuous ridges composed of glacial material deposited by meltwater currents in englacial tunnels. Their orientation is generally parallel to the direction of glacial flow, and they sometimes exceed 100 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. Some eskers would appear to form within part or completely within an englacial conduit that, on ice melting, becomes overlaid on subglacial sediments.

Some glacial landforms, such as drumlins and eskers, clearly indicate a landscape produced by subglacial processes. Other landforms, such as large channels known as tunnel channels or tunnel valleys, were produced subglacially by pressurized water flows directed toward the margin of the ice sheet.
