That seems like a very interesting book. Used copies are cheap, too...there's always been underprepared, dumb, or flat out unlucky people on mountains. A key point of this article is the "numbing" of how dangerous these things really can be just because you see a lot of pictures on social media. "If person 'X' can do it, so can I"! We post the highlights, but not the conditioning work, route research, and gear prep that goes into these things. Maybe we should be posting those.
I've made dumb decisions/mistakes, too. Or had to follow those made of a group, such as this past weekend going down a "shortcut" with little bootpath and a melting lake well, well below us. With people glissading when there's clearly a trickle of running water,and semi-exposed boulders and trees. I was necessarily unhappy and not participatory in that way of getting down.
