Mackenzie River in Canada's Northwest Territories

This view, acquired on Nov. 7, 2016, by the Operational Land Imager (OLI) on Landsat 8, shows a portion of Canada’s Mackenzie River Delta and the town of Inuvik, home to more than 3,000 people. A frozen highway — 194 kilometers (120 miles) long — runs between the remote outposts of Inuvik and Tuktoyaktuk along the river’s East Channel.
