Mackenzie Mountains Natural Region Mackenzie Mountains Natural Region Mackenzie Mountains is a limestone land of mountains and broad plateaux. The wide sweeping valleys of the Mackenzie and Liard rivers cut through this region.
Rivers slice through the extensive high plateaux and mountains, carving deep canyons.
Those of the South Nahanni River are best known, but similar breathtaking canyons are found along other rivers in this region. Dense boreal forests of white and black spruce, with stands of jack-pine or lodgepole pine, cover the rolling uplands and terraces above the Mackenzie and Liard river valleys. Extensive areas of alpine tundra are found throughout this region. Large mammals include grizzly bear, black bear, woodland caribou, Dall's sheep, mountain goat, moose, wolf, lynx and many more. Wood bison have been recently re-established in the Liard Valley.
