A Map of The Oak Ridges Terminal Moraine

Part I

A moraine is a glacially formed accumulation of unconsolidated glacial debris which can occur in currently glaciated and formerly glaciated regions, such as those areas acted upon by a past glacial maximum. This debris may have been plucked off a valley floor as a glacier advanced or it may have fallen off the valley walls as a result of frost wedging or landslide.

Moraines may be composed of debris ranging in size from silt-sized glacial flour to large boulders. The debris is typically sub-angular to rounded in shape.

The Oak Ridges Moraine is the best example of a Terminal Moraine in Southern Ontario with huge benefits to the inhabitants.
