Mont Saint-Grégoire (height: 251 m (823 ft)) is a mountain in the Montérégie region of southern Quebec, Canada. It is composed of essexite and syenite, strongly contrasting with the surrounding sedimentary rocks. The area around Mont Saint-Grégoire is known for its maple syrup production, as well as some wine production.
The name was changed in 1923 from Mount Johnson .
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.
