Kluane National Park and Reserve has the most genetically diverse grizzly population. Shown in this photograph is a Grizzly rooting for dandelions and other wild vegetables as fall sets in. Before 1935 the icy interior of the Yukon and southeast Alaska was unmapped, until The National Geographic Society sponsored the Yukon Expedition, largely conducted by plane lead by Bradford Washburn. In the distance here you can see the age old glacial dust blowing where the Slim's River once flowed. The deposited dust layers are known as loess. The Slim’s River Valley, Traditionally was known as Ä’äy Chù,is where this photograph was made in 2016. To the west is the highest peak in Canada, Mount Logan and its range of smaller mountains. It is the largest Ice Field in Canada, but it is retreating noticeably in places. When the Kaskawulsh Glacier on Mount Hubbard retreated, the Slims river and the southern end of Kluane Lake became a flat of dusty loess. The Glacial water that once fed the river reached a tipping point whereby it now flows down a south east facing slope to the Kaskawulsh River. Abutting the Kluane National Park and Preserve of Canada is the Tetlin National Park in Alaska, just over the border.
