Alaska is a cold unforgiving place.
Nanook of the North also froze to death. For those too young to remember him, there was a movie short about him and his sled dogs. But on a trip somewhere the weather was so bad and he did not make it.
I’m a bit young to remember the first release of that movie in 1922. It was the first documentary, filmed by Robert J. Flaherty around Hudson Bay (nowhere near Alaska). Nanook did, in fact, starve a few years later when caught by a blizzard.
