She made a lot of mistakes, but she survived! That shows she did some things right. The first thing she nailed was not panicking! Be scared if you have to but don't freak out. She kept her cool and seems to have had her priorities straight. She melted snow instead of eating it, avoiding death by hypothermia. She created a snow shelter to keep from freezing to death, plus had the presence of mind to be aware of possible avalanche conditions. It sounds like she had at least some minimal gear along including some food, a water bottle, and probably a pack with some supplies.

Obviously she screwed up but luckily for her, she didn't screw up to the point where the lesson killed her.
