Glaciations during the Quarternary Period have had a profound effect upon the landscapes of Nova Scotia. Glaciers changed narrow V-shaped tributaries to broad U-shaped valleys, and blanketed the province with a veneer of glacial deposits of varying thickness and form, in some areas up to 300 metres thick. The deposits were created by the action of the ice as it scoured, abraded and plucked at the bedrock during its advances across the country. Glaciers do not always erode earlier deposits. They can modify them or leave them alone. Glaciers have been described as "fickle" erosional agents.
In this Topic, the character and distribution of terrestrial glacial deposits are covered in some detail, in order to provide a basis for later topics and habitat descriptions.
