Picturing the Thelon : natures, ethics, and travel within an Arctic riverscape

With headwaters in Canada’s Northwest Territories, just east of the height land that separates the Hudson Bay and Mackenzie River watersheds, the Thelon River flows out of the boreal forest and east across the tundra and into Nunavut (Figure 1). The river stretches approximately 900 kilometres across habitat that is ideal for migratory herds of caribou and other large mammals like muskoxen, grizzly bear, wolf, and moose.
