So eskers and kames have som relationship in the origin of the sediment that make them up. Drumlins are of completely different processes. Much more could be said and all details are not completely understood when it comes to many glacial landforms and their formation.

Een drumlin (afgeleid van het Iers-Gaelisch: droimnín, een langgerekte heuvel) is een langgerekte heuvel die gevormd werd door een gletsjer.De lange as van de drumlin is parallel met de richting van de stroming van het ijs, de stompe kant wijst in de richting van waar het ijs kwam.

The village of Kemnay in Aberdeenshire, Scotland has a 5 km 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. An esker climbing over hills (including drumlins recording an earlier right-to-left ice flow direction) in Finland. The colours show elevation as measured from aerial Light Detection and Ranging (LiDAR) at 2m horizontal resolution. Drumlins - Drumlins (or fluted ridges) are geologic features where movement of the ice sheet smooths glacial sediment into elongated teardrop shapes. Drumlins align in the direction of the ice flow and are evident across most of the Puget Lowland. Drumlin: A glacier picks up and carries rock material.

They often occur together in fields, some with as many as several thousand individuals. Drumlins and drumlin swarms are glacial landforms composed primarily of glacial till.

drumlins, kettles, eskers, and glacial stream channels can be seen. Examples of these and other landscape features are enlarged at bottom right. Most of Washington’s population lives in this region—the glacial geology influences many aspects of daily life, including transportation, water supply systems, agriculture, and building regulations.

eskers are long meandering raised ridges found at the bottom of glacial valleys. They are formed by sub-glacial streams. Eskers are stratified in nature, as the rivers deposited the heaviest sediment at the bottom and the lightest material on top. As the glacier begins to melt, 11,000 years ago, sub-glacial streams begin to flow.
