Did she not have anything outside the sleeping bag? Doesn't that just end up trashing your bag?

depends what you sleep on, if you're on a bench or a piece of concrete or something then the bag should be fine. if you're on rocky ground you can clear a space to sleep pretty easily too
Did she not have anything outside the sleeping bag?
No, you can find cover for the rain in most places, and if you're cold wear all your clothes inside if you need to.
I'd try Lael Wilcox's tactics:
"Her sleeping system consisted of a Western Mountaineering Summerlite sleeping bag and a Western Mountaineering HotSac, a VBL which doubles in this situation as an emergency bivy. This is equipment which she has been using for years. The sleeping bag has a busted zipper and the fabric is ragged and fragile. It has been repaired by hand in many places. On at least one night, she slept in her helmet, which she discovered was a comfortable solution to supporting her head and staying off the ground. She did not pack a sleeping pad."
