. 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
