Origin Of The Oak Ridges Moraine
The Oak Ridges Moraine is a geological landform that runs east-west across south central Ontario, Canada. It developed about 12,000 years ago, during the Wisconsin glaciation in North America. A complex ridge of sedimentary material, the moraine is known to have partially developed under water. The Niagara Escarpment played a key role in forming the moraine in that it acted as a dam for glacial meltwater trapped between it and two ice lobes.
In order to understand the process by which the moraine formed, it is necessary to understand the physical geography in which it currently exists (that is, its physiography), and the layers of sediments found within it (the stratigraphy of the moraine).
