Robinson Esker

Robinson Esker is a prominent glacial deposit in Canada. An esker is a long ridge of sand and gravel deposited by meltwater flowing through or beneath a glacier.

The deposit formed through glacial erosion and deposition, with meltwater carrying sediment and leaving it behind as ice retreated. Its shape records the movement of water within a former glacial environment.

It demonstrates how glaciers can both erode landscapes and build ridges from transported sediment. Robinson Esker is therefore useful as a visible example of past glacial processes in Canada.

An esker is generally made of unconsolidated sand and gravel rather than one solid bedrock ridge. Its loose sediment was deposited by glacial meltwater and may be vulnerable to erosion or excavation.
