Deglaciation of the central Nain-Okak Bay section of Labrador. Arctic
ABSTRACT. Glacial erratics on the highest peaks of the Nain-Okak Bay section of Labrador indicate that at one time the entire area was completely glaciated. This complete ice cover is tentatively correlated with the Torngat Glaciation. A subsequent ice advance from the interior of Labrador, during w...
