Foster Upland
Foster Upland forms part of the rocky Churchill River highlands, where long ridges rise among lakes, bogs and fens. Glacial deposits cover much of the old bedrock, in places forming prominent sandy ridges. Black spruce grows both on thin-soiled heights and in wetter ground, while jack pine favours drier sands. Streams drain from the upland towards the lake country to the northeast, including Reindeer and Wollaston lakes.
