A fjord is a glacier valley with tides in it. The Saguenay fjord is distinct because of the sea life and the length of it.
It is 100 km long from Chicoutimi to Tadoussac . L'Anse-Saint-Jean is located mid distance from both cities.
Immense glaciers engraved the landscape of this beautiful region, creating single abrupt cliffs landscape, plateaus and sharp-edged peaks. The Saguenay fjord has an average width of 2 kilometers and a depth of 270 meters. At the mouth of the Saguenay River, in Tadoussac, the river is "blocked" by a glacial bolt, permitting only a thin layer of water of approximately 20 meters through.
The top level waters of the Saguenay, relatively warm and fresh, slip literally on a very salty and very cold sheet of bottom water. This exceptional ecosystem permits the juxtaposition of an arctic marine animal-life with other species that live in a more moderate environment.
