It was plainly a not so smart or inexperienced move. Hopefully Homeboy learns his lesson. I imagine someone else might have but that is usually because there is something about people in the Northwest climbing across glaciers unroped quite often. I dont know what to think about it sometimes other than possibly dumb, inexpeperience, lazy\lackadaisical, or arrogance. I have been guilty of all these myself but I don't think I would have done what this guy did period. Especially in Jeans and Tshirt so late.
Bottom line is good thing he is ok.
