Eskers

This page was contributed by Dr Frances Butcher from Sheffield University. What is an esker? Eskers are ridges made of sands and gravels, deposited by glacial meltwater flowing through tunnels within and underneath glaciers, or through meltwater channels on top of glaciers. Over time, the channel or tunnel gets filled up with sediments. As the …

Introduction to Glaciofluvial Landforms

“Fluvioglacial” or “glaciofluvial” means erosion or deposition caused by flowing meltwater, from melting glaciers, ice sheets and ice caps. Glacial meltwater is usually very rich in sediment, which increases its erosive power. Glaciofluvial landforms include sandar (also known as outwash plains; they are braided, sediment-rich streams that drain away downslope away from a glacier), kames …

Glaciofluvial landforms

Glaciofluvial landforms are landforms created by the action of glacier meltwater. They can be erosional, or depositional landforms, and can form underneath, on top of, in front of, and around the edges of former glaciers.

Meltwater channels

What are meltwater channels? Each year, glaciers melt. Meltwater channels are erosional features, cut into rock and sediment by flowing water beneath or close to ice-sheet margins1,2. They can cut sizeable troughs, meaning that they are very visual indicators of the location of the former ice margin. Meltwater channels can therefore be used to work …
