Glacial landscape, Torngat Mountains, northern Labrador.
The Torngat Mountains of northern Labrador contain some of the finest examples
of alpine glacial landforms in Canada. The bowl-shaped depression in the
centre of the photograph is known as a cirque. During ice ages, a glacier
grows in the cirque and slowly excavates the depression.
The mountain, composed of ancient rocks of the Canadian Shield,
is known as Cirque Mountain.
