Glad she made it through.

A very serious business, being exposed in those conditions. I assume the lady had some significant health/mobility issues as an underlying factor. Inexperience in the care/feeding of a sled? Maybe; they can be finicky buggers at times.

If the news report is accurate (!?) the first responders fired up a PLB to ramp up the search. This suggests extremely limited comms in the area.

Edit: +1 on "Nuts!"
