The Dempster Highway is over 700km of gravel road running from Dawson in the Yukon to Inuvic in the Northwest Territories. In the winter you can continue on an ice highway over the Arctic Ocean to Tuktoyaktuk. The highway is one of the most beautiful drives in the world. In this image, made around 75km from the southern end, we see the worn-down but colourful Ogilvie Mountains. The name comes from William Ogilvie, a surveyer in the days of the Klondike gold rush. These southern mountains took a real beating in the last ice age, but the Ogilvie range accompanies you for about 300km of the drive and the northern end of the range escaped glaciation.
