. This, according to some, makes the Torngats, as mountains, "distinct compared to the surrounding Precambrian Canadian Shield," though they are ultimately composed of shield rock. Evidence of this dramatic cordilleran folding and faulting characterizing the Torngat Mountains can be seen distinctly in rocks where the North American Craton long ago collided with the Nain Craton, later exposed in cross-section by glacial scouring, especially at Saglek Fjord.

Glaciation

The ranges of the Torngat Mountains are separated by deep fjords and finger lakes surrounded by sheer rock walls. The fjords were produced by glaciation. The Laurentide Ice Sheet covered most of the mountains at least once, however during the last ice age the coverage was more limited. Currently, there are over 100 active small mountain

Ecology

Flora

The Torngat Mountain tundra is characterized by sparse cover of arctic sedges, grass, lichen, and moss. Patches of mixed arctic evergreen and deciduous shrubs can be found on sheltered south-facing slopes, increasing in prevalence as one moves south.

Fauna

The tundra provides seasonal habitat for

Notably, a billion-year-old coal seam (based on algae, not peat swamps) was discovered in the Torngat mountains on the Newfoundland Coast as part of the filming of the series. ''Backcountry Magazine'' ran a feature story written by Drew Pogge in 2009 on steep skiing in the Torngat Mountains, notably first descents in Nachvak and Saglek fjords, as well as on the Caubvick massif.
