The big thing that jumped out to me (and others as noted) is your clothes. Here is what I would bring for a February start:

Hiking
-REI Sahara Pants Hiking
- Mid Weight Base Layer
- 100 weight Fleece
- Darn Tough Socks
- Wool Beannie
- Glove liners (TNF) and Mitts (Borah Gear)
- Rain Pants and Jacket - add/ remove as needed


Camp Only
- Heavy base layer top and bottom
- Montbell Alpinelite Down jacket- Outdoor Research Down Beannie
- Dry sleep socks
- Crocs (these are heavenly when your shoes are wet in the winter)
- Possibly a spare set of gloves but probably not.
