In which Canadian provinces or territories do the Laurentian Highlands lie?

Answer 1

The Laurentian Highlands are part of the plateau and dissected southern rim of the Canadian SHIELD in Québec. Viewed from the valleys of the Ottawa and St Lawrence rivers, the south-facing escarpments of the Shield give the appearance of mountains 500-800 m high; looking across the plateau, the relief is more moderate and subdued. These scarps mark the dramatic southern edge of the highlands.

Although the other limits are less well defined, the highlands may be considered to extend 100-200 km northward from the scarps and to stretch from the Gatineau River in the west (mean elevation 400 m) some 550 km to the SAGUENAY RIVER in the northeast. Here they attain their maximum elevation north of QUÉBEC CITY in the Réserve faunique des Laurentides (over 1000 m). Individual summits rise above the plateau surface: Mont Sir Wilfrid (783 m) and Mont TREMBLANT (968 m) in the west, Mont Sainte-Anne (815 m) at Québec, Mont Raoul-Blanchard (1166 m), Mont Bleu (1052 m) and Mont des Conscrits (1006 m) in Réserve faunique des Laurentides. Cap-Tourmente (579 m) and Mont des Éboulements (770 m) are dramatic examples of the scarp face as it drops precipitously to the St Lawrence River.

Answer 2

The Laurentian Highlands consist of a landmass that extends from the Gatineau and Ottawa rivers in the west to beyond the Saguenay River in the east. Elevation ranges from 400 metres to more that 1000 metres (about 1300 to 3300 feet) in Laurentides Provincial Park north of Quebec City. These highlands are part of the southernmost portion of the Canadian Shield within Canada. They correspond closely with Quebec's Grenville geological province.

Answer 3

The Laurentians are in Quebec. My grandparents had a weekend home there.
