Mount Washington has claimed at least 137 victims since 1849. It is called the most dangerous small mountain in the world. http://www.backpacker.com/october_08_americas_10_most_dangerous_hikes_mt_washington_nh/destinations/12622
I know a guy who got caught in snow storm on Mt. Washington when he was in his sixties. Not a pleasant experience, but he survived.
Yes, because of its sudden, hard to predict, and severe weather changes. Novice hikers frequently underestimate how severe the weather can be, and how much gear you need to survive in 40 degree condensing water with a 40 mph wind. Particularly if you started your hike in calm air at 80 degrees so shorts and a T shirt seemed like a good idea.
And even some experienced hikers think they can keep hiking in winter conditions where winds can be over 80 mph. They can't, and even crawling is next to impossible safely in open areas.
Wow, I mean it’s great we have access to these great places but it doesn’t mean we’re all experienced enough to deal with all of the risks. OTOH, I’d still rather keep the freedom to make those decisions rather than have the nanny state make the call. Tragedy happens and we’d like to minimize that but the freedom to make those decisions is paramount.
