Great Slave Lake

Great Slave Lake and Lake Athabasca.

Great Slave Lake is a large deep lake in the Northwest Territories. It is a rift lake. It is one of the largest lakes in the world, and the deepest lake in North America.

Yellowknife, the capital on the Northwest Territories, lies on its north shore. Hay River, the northern terminus of the North American railway grid, is situated on the south shore, at the mouth of the Hay River. There is an intermodal terminal there, from which general cargo and international shipping containers are loaded from rail cars and transport trucks, to barges. Those barges are pushed or towed, by tugboats, throughout the Mackenzie River basin, the Beaufort Sea, and Canada's Arctic Archipelago.
