Moving northward into an area where eastern Quebec meets the western boundary of the Labrador subprovince of Newfoundland, we see next a segment of the Canadian Shield. This is the Labrador Fold Belt, made up of tightly folded sedimentary rocks wedged between two granite complexes. The present surface is strongly glaciated, leaving low hills and lakes. The high northern latitudes favor an arctic-like vegetation assemblage called tundra. This inhospitable landscape is very sparsely populated, with a few small towns build near iron mines.
Tundra again is typical of Canadian island surfaces well above the Arctic Circle.
In this scene, the major land body is Melville Island, made up of Paleozoic sedimentary rocks and characterized by deep embayments that are valleys gouged out by continental glaciation of the Pleistocene, now occupied by the Arctic Sea which even in this July view is still completely frozen. Winter still remains in this March scene in the Province of Manitoba just north of North Dakota. Dominating the scene is Winnipeg, appearing black against the light snow because of snow removal and melting in that large city. The dark areas that extend over the right third of the scene are the western edge of the Precambrian Canadian Shield. Pine and spruce are the prevalent trees in this part of the Shield.
