Its summit stands {{Convert|411|m|ft|0|abbr=on}} above sea level. This mountain is largely covered with deciduous forest dominated by sugar maple. Some apple orchards are raised on lower slopes. GeologyMont Yamaska is composed of igneous rock and hornfels. The igneous rock is mostly mafic with much gabbro, essexite, and a titanium-rich pyroxenite. Mont Yamaska might be the deep extension of a vastly eroded ancient volcanic complex, which was probably active about 125 million years ago.[2] The mountain was created when the North American Plate moved westward over the New England hotspot,[2] along with the other mountains of the Monteregian Hills that form part of the Great Meteor hotspot track.
