Qausuittuq National Park encompasses 11,000 km2 on northern Bathurst Island and smaller surrounding islands in Nunavut. It also includes the waters of May Inlet and Young Inlet. Pronounced Kow-soo-ee-took, the name of this park translates to “the place where the sun doesn’t rise” in Inuktitut. It is bordered to the south by Polar Bear Pass National Wildlife Area, and together these two zones protect a large, ecologically intact area in the Canadian Arctic Archipelago. Qausuittuq was established on 1 September 2015 as Canada’s 45th national park. It represents the Western High Arctic Natural Region, the 38th natural region of the 39 that constitute Canada’s national parks system.
Rivière Saint-Maurice, 563 km long, rises upstream from Réservoir Gouin, 200 km west of Lac Saint-Jean, Québec. It drains a basin of 43 300 km2. After its confluence with Rivière Manouane, it feeds Réservoir Blanc and then takes in the Vermillon, Trenche, Croche, Mattawin and Mékinac rivers.
A continental divide is a ridge or natural boundary of elevated terrain that separates the drainage basins of a continent. Each drainage basin contributes its water to river systems, which in turn flow into distinct larger bodies of water, such as oceans. The main continental divide in Canada follows the ridge of the Rocky Mountains.
