It was late when I first posted this...

"We are still looking for an example of someone leaving a pack at a col and then getting into trouble higher up."
There's a sort-of (subjects got themselves out of their pickle) example in Laura and Guy Waterman's book
Wilderness Ethics (which IMHO--not that I'm telling anyone what to do!
--should be required reading for White Mtn. trampers). In the Chapter "Winter Above Treeline," page 183 in my edition, they recount a 1968 winter Presidential traverse attempt, where a father (Guy) and his son (Johnny?) leave their packs on the south side of Jefferson in sketchy weather "...and they delighted in the freedom of an easy dash uphill without packs and with the wind at their backs."
On their descent, however, the clouds rolled in, the wind picked up, and both became completely disoriented. Complicating matters, the "father" had left his compass in a shirt which was stowed in his pack. They were left to guess on the correct route down, and when finally able to ascertain exactly where they were, realized they were 180 degrees off course, on the north side of the mountain.
After another long plod across the Jefferson snowfield, they were eventually reuinited with their by now ice-encrusted packs.
Now everyone, go out and buy the book from The Mountain Wanderer!
(FWIW, I think there's a big difference between leaving one's pack above treeline and, say, leaving it at Galehead Hut in order to climb Galehead, but that's just me...)
