Based on the comment about the electronics, GP is likely referring to Kate Matrosova, who perished in positively appalling conditions, even by the very low standards of winter in the Whites.

She died just off the Star Lake Trail, having ascended to the ridge via the Valley Way, which hits the ridge line at Madison Hut (4800', or much lower than the summit of Washington at 6288'). My partner and I have bailed off pretty much exactly her route in the summer when the winds were too high for our experience and fitness levels when we popped up out of the lee side of the ridge line on Adams.

Anybody who wants a really well researched case study should read Ty Gagne's book on her trip and the subsequent rescue attempt.

Incidentally, my partner and I climbed Washington on a guided trip the weekend after she died. The weather was so good the guides had their cameras out to take pictures. The extremes in the Presidentials are no joke, as stated, but can also result in some beautiful days.

Yeah, that's the case and the book I was talking about.

The actual accident, while obviously very tragic, wasn't especially interesting. Basically don't try to do a Presidential Traverse during the worst weather in about 20 years. It was actually a different situation from the more common cascading failures mode of accidents.

She made a grave error by deciding to drive up to NH that weekend and a fatal one by continuing above treeline. Even Rick Wilcox (owns local climbing gear/guide store and has summitted Everest) basically says in the book that she was well enough prepared but shouldn't have been out that day.

That said there were definitely lessons around just because you have a lot of experience, don't assume you understand the local situation when you have little to no experience there.

But the search and rescue account was morbidly fascinating. Also demonstrates that locator beacons won't always save you. (She admittedly didn't use it properly but I doubt it would have made a difference given the weather.)

I think the big takeaways for my partner and I were a little more nuanced. With all respect to Kate Matrosova and acknowledging that we don't have any knowledge of her thoughts that day:

0) Her mileage to the top of Madison was off by about a mile on her written plan. Not a good place to start for an ambitious day.

1) Most of her prior experience was guided where somebody else was responsible for making the decisions. I am fully prepared to believe that she had the physical experience, but would suspect that she lacked the decision-making experience that would have saved her.

2) She died heartbreakingly close to Madison Hut. If she'd turned around 30 to 60 minutes earlier, she might have made it to the relative shelter of the hut with enough energy left to warm up and get back below treeline on the Valley Way, which is quite close to the hut. Speculation, I know, but I can't help but wonder.

We talked a lot about the decision-making because we could both see ourselves having a go in the same circumstances owing to our inexperience (we independently thru-hiked the AT, but we aren't mountaineers). Reading it was a really useful case study for us and helped think through identifying when we're about to cross the line from adventure to peril.

If you didn't know, he's got a second book out, btw. Gonna crack it open next :-)

I know he has another book out which wasn’t available when I bought this one. I’m actually involved with a winter hiking program which is how I found out about this one because I’m usually involved with leading winter trips in New England.

To your point, I agree and think I touch on most of them upthread. Weather is definitely an an important consideration. She hadn't mostly been involved in making tough calls.

And, yeah, she had opportunities to bail after driving up from NY. But clearly she wasn't going to do that prior to seriously going for Adams at which point it was too late given the weather.

BTW, when I said "you" before I didn't mean you @ghaff. I know you know these things; that was for the majority of HN folks whose experience is likely to be with taller but still less dangerous peaks. I apologize for the lack of clarity.
