In some instances, eskers can occur draping drumlins in some places at an oblique angle to the drumlin long-axis orientation. Drumlin are elongated whale-back hummocks composed mainly of boulder clay with their elongation in the direction of the ice flow.

Drumlins eskers

Drumlin: A glacier picks up and carries rock material. This probably accumulated along the edge of the ice sheet. Ice pushing against it probably rode up and over it shaping it into  elongate, oval hills called drumlins. Drumlins probably developed as the ice sheet pushed southward. Drumlins are short (avg.

In the north the esker consists of single and multiple ridges: where multiple, the ridges.

Landforms that result from these processes include moraines, kames, kettles, eskers, drumlins, and plains Esker, a long, narrow, winding ridge composed of stratified sand and gravel deposited by a subglacial or englacial meltwater stream. Eskers may range from 16 to 160 feet (5 to 50 m) in height, from 160 to 1,600 feet (500 m) in width, and a few hundred feet to tens of miles in length.

They form near the margin of glacial systems, and within zones of fast flow deep within ice sheets, and are commonly found with other major glacially-formed features (including tunnel valleys, eskers, scours, and exposed bedrock erosion). Eskers are glaciofluvial deposits from sediment carrying subglacial tunnels. As the water emerges from a tunnel at the bed of an ice sheet or glacier it will slow down. Since the sediment movement depends on water velocity the sediment will be deposited.
