Mont Yamaska

Mont Yamaska, in southern Quebec, is one of the Monteregian Hills and rises 411 meters above sea level. Known in Abenaki as Wigwômadenek, it is largely cloaked in deciduous forest dominated by sugar maple, with apple orchards on its lower slopes. The mountain is geologically notable for its igneous rock and hornfels, including abundant gabbro and essexite, a titanium-rich clinopyroxenite called yamaskite, and a small area of nepheline syenite. It may be the deep, eroded remnant of an ancient volcanic complex formed about 125 million years ago as the North American Plate moved over the New England hotspot within the Great Meteor hotspot track.
