The Globe article said her face was bashed up a bit, so it sounds like she was injured from being picked up and dropped by the wind; unable to move. I don't think the conjecture on a snow cave or getting to the hut is relevant in her case (but would be helpful if she weren't injured). Assuming you can move at all, why not just get below treeline and hunker down there?
A 0 to -20 degree sleeping bag plus her insulating clothes, winter pad and maybe a bivy (not much snow melting going on in those temps so maybe not needed) would probably have saved her life but is unthinkable for the typical fast and light winter peakbagging types we have in NH.
