From the World Heritage inscription:
The Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek national parks and protected areas along the boundary of Canada and the United States of America are the largest non-polar icefield in the world and contain examples of some of the world’s longest and most spectacular glaciers. Characterized by high mountains, icefields and glaciers, the property transitions from northern interior to coastal biogeoclimatic zones, resulting in high biodiversity with plant and animal communities ranging from marine, coastal forest, montane, sub-alpine and alpine tundra, all in various successional stages. The Tatshenshini and Alsek river valleys are pivotal because they allow ice-free linkages from coast to interior for plant and animal migration. The parks demonstrate some of the best examples of glaciation and modification of landscape by glacial action in a region still tectonically active, spectacularly beautiful, and where natural processes prevail.
Wow. I can’t even express how amazing Kluane National Park was. I had a the pleasure of flying over the ice fields on two separate days in both a helicopter and a fixed wing airplane. The images were incredible. I have so many I have no idea how I’m ever going to be able to pick the best ones. Kluane doesn’t get as many visitors as the parks on the Alaska side of the border because it is more difficult to reach, but it is well worth the effort if you can make the trip.
