The Nassagaweya Canyon is a deep valley that runs between the main Escarpment and a large rocky outcrop known as the Milton Outlier. the outlier was once connected to the main body of the Escarpment but became separated from it by the erosive action of an ancient stream. At the end of the last ice age, between 13,500 and 12,000 years ago, the valley became a discharge channel, carrying torrents of split debris-laden water released by the melting ice. It was the turbulent action of these meltwaters that carved the canyon into its present distinctive form.
