description Laurentian Massif Overview
The Laurentian Massif is an extensive upland region of southern Quebec formed from ancient Precambrian rocks of the Canadian Shield. Long erosion has produced rounded, forested hills and relatively modest elevations, generally below 1,000 meters, rather than sharp alpine peaks. The region contains numerous lakes and rivers and is used for forestry, outdoor recreation, vacation communities, and winter sports at resorts north of Montreal.
help Laurentian Massif FAQ
Where is the Laurentian Massif located?
The Laurentian Massif occupies much of southern Quebec and forms part of the Canadian Shield. It is associated with the Laurentian Mountains north of the St. Lawrence River.
Why does the Laurentian Massif have rounded hills instead of sharp peaks?
The region is made from very ancient Precambrian rocks that have been worn down by long-term erosion. As a result, its forested uplands are generally rounded and modest in height, often below 1,000 metres.
Is the Laurentian Massif part of the Canadian Shield?
Yes. The Laurentian Massif is an exposed upland region of the Canadian Shield, one of the oldest large rock areas in North America.
How is the Laurentian Massif different from the Alps?
The Laurentian landscape is older and more heavily eroded, with wooded ridges and rounded summits rather than the high, jagged relief of the Alps. Its elevations are generally below 1,000 metres, while many Alpine peaks exceed 4,000 metres.
