The bluffs are formed from eroded drumlins, teardrop-shaped hills of glacial till that were deposited and shaped by glaciers during the most recent ice age. The erosive power of wind, rain, snow, and waves has formed the landscape into sharp pinnacles.
Why are Scarborough Bluffs eroding?
As the waters of Lake Ontario move against the Bluffs, material is washed away from the bottom of the Bluffs (slope toe). This over-steepens the slope toe leading to instability further up the slope.
Why are the Scarborough Bluffs unstable?
The Bluffs are unstable due to several natural processes, including wave action from Lake Ontario, surface water runoff and over-steepening of the slope face to precipitation, wind, and freeze-thaw cycle. The Bluffs are affected by these natural processes all year long.
