Geology

It is thought that Mont Saint-Grégoire might be the deep extension of a vastly eroded ancient volcanic complex, which was probably active about 125 million years ago.[1] The mountain was created when the North American Plate moved westward over the New England hotspot,[1] along with the other mountains of the Monteregian Hills. It forms part of the vast Great Meteor hotspot track.
