Looks like the weather turned on them. I wonder what the author is speaking of when he mentions that the lost hikers couldn't find the trail? I've been on Whitney several times - the last few miles are pretty much a knife edge on the mountain, with a pretty steady wind coming up the west face.

Maybe they're talking about the turn-off that heads back to the base camp and lower elevation? That tends to be a snowpack anyway, so if you've got snow covering the tracks on that trail...

Either way, it's a doozy of a hike. Hope they found the shelter at the summit - if not, there are a bunch of boulders that would serve as a good wind and snow break. Let's hope it turns out well.
