Laurentian

In the southern part of the Canadian province of Quebec, the Laurentine Mountains or Laurentides stretch. The mountain range originates in the west and extends along the northern banks of the Ottawa and St. Lawrence rivers to the east. It is part of the Lawrence Upland. Refers to the oldest massifs of the globe, includes rock deposits of about 540 million years old, belonging to the Precambrian era.

The center of the Grenville orogen is the Laurentides, whose age reaches about a billion years. The highest mountain has a height of 1166 meters and is located in the north-east of the city of Quebec - this is Raul Blanchard. From the mountain lakes, the Laurentides originate the rivers Gatineau, L-Assoncion, Ljèvre, Montmorency Falls, Du Nord and Saint-Maurice.

On the other side of the St. Lawrence River, in northeastern New York State, the Laurentian Mountains pass into the Adirondack Mountain Range. Despite the fact that the administrative region in which the Laurentides are located is officially considered the province of Quebec, the Laurentian Mountains reach the city of Boncher in northeastern Ontario, crossing the administrative regions of Capital Nacional, Utaue, Lanodier and Morisy.
