One look at the picture on this post has me wondering. Some of the terrain even allowing for the narrow trail is clearly class 3 and class 4 terrain. She might even get into some ‘easy’ clas 5 and all this is snow covered. Back packing and hiking DOES NOT prepare you for that. The person who posted this pic almost certainly doesn’t know how to climb, belay, lead , second or mutipitch. She should really watch it, there are mountains in the west were you can find yourself in this terrain really quickly unlike the east were doing the AT trail from Georgia to Maine you will never see any of that even on katadin.
