interesting thread. I was just talking about this with a friend. I have a 1969 amc guide, which has an entire CHAPTER devoted to winter hiking, equipment, and conditions. This guidebook takes a much more serious view of winter hiking than is taken now. It says people should carry a sleeping bag, in case of 'unexpected night out', in addition to stove, etc. Basicly, you were just about expected to have everything to camp out in the winter. At the time, this was probably considered common sense.
I was thinking about why this change in attitude would be the case. I think back then, hardly anyone went out hiking in the winter, especially up the big peaks. The trails were unbroken, and it could take all day(at least), just to get up on a ridge. Having to biviouac or camp out could probably be a reasonable expectation to have to do. Nowadays, with the increase in hiking traffic, all the trails usually are broken out early in the morning, with smaller snowshoes pushing the snow down farther and more firmly, and the last few winters, I have been able to crampon up the high peaks in a fraction of the time it would have taken previously. This has led to a sense of security regarding winter hiking. Most of the time, this security is correct. One can blast up to a high summit, have much less fear of losing the trail than years ago, and blast back down in a hurry, especially if need be.
The trouble is, you can stick your neck out so easily and high up, that if something DOES happen, you are way the hell out in the middle of nowhere, lost, without the equipment necessary to spend the night. Once lost, you are just as lost and in as dangerous a condition, as you were back in 1969. If you have to bushwhack, the crampons or small snowshoes you have, that are great on packed trails, are very inadequate for flotation in deep snow.
Another thing,
Years ago, people knew how to build a fire, and would build them when lost. Someone would always have a campfire going. I don't even know if people are carrying matches anymore, and if so, don't seem able to have the skills to start a fire if they need to in the winter, with wet branches and snowy conditions.
I think more of this kind of thing(people getting lost, deaths or lucky escapes) will continue to happen if people are going to be hiking with the continued 'comfort level' that winter hikers have grown accustomed to, without realizing the conditions they can suddenly be trapped in if they get lost, pinned down by wind, or otherwise have to spend the night.
On the other hand, hiking lighter enables one to go faster, and get away with it 99 percent of the time. It is an interesting debate.
If anyone can get hold of the older guidebooks, or some other older winter hiking material, you will notice how much more seriously they take it.
just a few thoughts while I'm waiting for my programs to run
