Moore Esker

Moore Esker is a significant glacial deposit in Canada. It forms a long, well-defined ridge made from sediment deposited by retreating ice sheets.

Meltwater flowing through or beneath retreating glacial ice carried sand, gravel, and other sediment. When the ice withdrew, the deposited material remained as a raised ridge called an esker.

It is notable for its extensive length and clear ridge shape. Those features make the landform a useful example of how glaciers and meltwater reshape the landscape.

An esker is usually a winding ridge deposited by meltwater streams beneath or within glacial ice. A moraine is sediment pushed or left directly at the edge or sides of a glacier.
