Cumberland Island (Saskatchewan)

Cumberland Island, also known as Pine Island, is a small island in the Saskatchewan River Delta in the east-central region of the Canadian province of Saskatchewan. The Saskatchewan River Delta is one of the largest active inland deltas in North America. Cumberland Island is situated between Cumberland Lake to the north and the Saskatchewan River to the south. The Tearing River runs along the eastern edge of the island and Bigstone River along the western edge. The Bigstone River separates Cumberland Island from Spruce Island to the west. The island is in the Mid-Boreal Lowland region, which consists of mixed coniferous and deciduous forests of white and black spruce, jack pine, tamarack, trembling aspen, balsam poplar, and balsam fir.

Cumberland Island's location was important to the fur trade as it sat on the canoe route that brought furs from the west to the Hudson Bay. In 1774, the Hudson's Bay Company had set up its first inland factory on the island.
