This creates depositional features including drumlins, moraines, kames, kettles, eskers, and outwash plains. Glaciers pick up and transport a huge load of debris as they advance. When they retreat, this debris is deposited where the ice melts (Tarbuck 163). eskers are long meandering raised ridges found at the bottom of glacial valleys.

Because they have been streamlined by flowing ice, scientists often use them to understand past glacier flow directions. They are longest in the direction of flow. Drumlins and drumlin swarms are glacial landforms composed primarily of glacial till. 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 ). As nouns the difference between drumlin and esker is that drumlin is (geography) an elongated hill or ridge of glacial drift while esker is a long, narrow, sinuous ridge created by deposits from a stream running beneath a glacier.

Much more could be said and all details are not completely understood when it comes to many glacial landforms and their formation.

they go over deposited moraines, they form new ones, and can reshape them into drumlins. Drumlins are steep going up the glacier, and gentle going down.
