Ice fields and lofty mountains make up 75 per cent of Kluane National Park and Reserve, part of which is in the Mount Logan Ecoregion. The summit of the Icefield Ranges runs around 4,575 meters, while Mount Logan, Canada’s tallest and North America’s second tallest mountain.

Kluane’s other 25 per cent, forming the eastern edges of the park, belongs in the St. Elias Ecoregion. This is the area that the vast majority of visitors come to see – a realm of forested valleys, alpine meadows, mountain slopes tangled with alder and willow, swift rivers, and rocky peaks.

Somewhere over Kluane that moist Pacific air meets dry Arctic air, producing a variety of climatic conditions. These conditions make Kluane perhaps the most biologically diverse area in Northern Canada: it is home to more than 200 species of plants.  But of greater interest to most visitors are the many high-profile animals that live there. Some 4,000 Dall’s sheep inhabit the front-country slopes. The park also boasts a high concentration of grizzly bears.
