We actually had one of your countryman, well sort of, he was a pretty nimble 70 year old from Alaska and had hunted extensively there owning his own Piper Cub for access to a lot of areas. The afternoon we flew in and set up our camp was settled weather with no sign of snow, pleasant enough looking area to hunt albeit steep in places. The Alaskan commented even then that he thought he was out of his league in this area, he didn't know what was coming. After an overnight high wind and rain storm turning to snow for a day and a half I think he resigned himself to hell. When he appeared out in the snow after the storm settled down with denim jeans on our hearts skipped a beat. Jeans might be okay in Alaska but you will die in them in our high country. Fortunately he did have a pair of camo waterproof over trousers which saw him through.
Unless you set off an ELB you are in the area until the chopper arrives for the arranged pick up a week later and they won't come in during a storm.
