How was the Scarborough bluffs formed?

The Scarborough Bluffs were formed through a combination of glacial activity and erosion. During the last Ice Age, glaciers carved out the landscape, depositing sediment that eventually became part of the bluffs. Over time, water erosion from Lake Ontario and wind have shaped the bluffs, creating their distinctive cliffs and ravines. Today, the bluffs continue to evolve due to ongoing erosion and natural processes.
