As Canada's largest province, Quebec is over twice the size of the U.S. State of Texas.
Most of Quebec is covered by the Canadian Shield, a rocky, but generally level landscape of plains and plateaus, covered by large areas of coniferous (evergreen) forests, all crisscrossed by hundreds of rivers and countless thousands of lakes.
During the last Ice Age, layers of ice moved slowly across the Ungava Peninsula of northern Quebec, flattening the rock below it. When the ice retreated (or melted) the land below was left almost level. Today this stark area (tundra) is treeless, with a permanently frozen subsoil.
In the far-north, the Torngat Mountains dominate the landscape along the border with Labrador. These treeless mountains are indented by fjords and lakes. Quebec's highest point is located here; Mt. D'lberville stands at 1,652m (5,420 ft) high.
The Laurentian Mountains in southern Quebec are one of the oldest mountain ranges on the planet. These rounded peaks are covered by dense forest and home to many large lakes and numerous rivers.
Quebec's Gaspe Peninsula extends into the Gulf of Saint Lawrence, and contains the Chic-Choc Mountains, a rugged extension of the Appalachian Mountains.
The massive St. Lawrence River links the Atlantic Ocean with the Great Lakes and is Canada's most important economic highway. The St. Lawrence Seaway (in and along the river) is a system of canals and locks that facilitate access to the Great Lakes by ocean-going vessels from around the world.
The Saint Lawrence Lowlands stretch along both sides of the river. This low-lying and relatively flat landscape includes Anticosti Island, and the smaller islands within the Saint Lawrence.
The diversified geography of the Province of Quebec accounts for over a million lakes (mostly small) and tens of thousands of rivers and streams. The most significant ones are identified on this map.
