A narrow channel cut into the bedrock or deposits, either underneath or along the front of an ice margin, due to meltwater streams.
=================================
Due to the pressure from the glacier, they are highly erosive. I

Kame
A steep-sided mound of fluvio-glacial sand and gravel.
=================================
Material collects within a depression on top of the glacier. When the glacier melts completely, the material is left on the valley floor. This leaves a mound of fine

Esker
Long winding ridge of glacial deposition.
A mould of glacial meltwater channels.
=================================
Material is deposited when the subglacial meltwater channel loses energy. Due the high hydrostatic pressure, the mound builds up and retai

Outwash Plain / Sandur
A flat expanse of fluvio-glacial debris in front of the glacial snout.
=================================
When a glacier recedes, meltwater is released.
The meltwater loses energy and it deposits material in front of the glacier (sorted and stratified). T

Kame Terrace
A flat, linear deposit of fluvio-glacial sand and gravel at the valley sides.
================================
Valley sides radiate heat in summer, melting the
edge of the glacier and forming meltwater
streams which deposit sediment.
When the glacier r

Kettle Hole
A circular depression, often forming a lake in an outwash plain.
=================================
As the glacier retreats, detached blocks of ice remain on the sandur. Meltwater streams cover them in deposits. When the ice melts, the debris subsides. Th

Proglacial Lake
A lake formed in front of the glacier snout.
=================================
Formed by the damming action of a terminal or recessional moraine during glacial retreat, or because hills block the escape of meltwater.
