help White Esker FAQ

What is White Esker?

White Esker is a light-colored glacial ridge in Nunavut, Canada. Its pale sediments stand out against the surrounding Arctic tundra.

How was White Esker formed?

An esker is a long ridge of sand and gravel deposited by meltwater flowing through or beneath a glacier. White Esker therefore records the movement and drainage of ancient glacial ice.

Why does White Esker look white?

Its light appearance comes from the color of the sediments exposed along the ridge. Against darker tundra and seasonal vegetation, the pale glacial material is especially easy to see.

Is White Esker a mountain or a volcanic formation?

No, it is a glacial landform rather than a volcano or conventional mountain. Its ridge shape was built from sediment carried by meltwater associated with retreating ice.
