Thank you for your in-depth reply. I really appreciated all the insight and advice. And yes, I was planning on bringing a bladder which holds 2 liters and then an extra canister for another liter of water and I planned on using the tablets to purify the water. My two sons are 14 and 17, both boy scouts, so I'm thinking that this trip will be okay. We all snowboard so we're all comfortable with the snow.

Regarding the oranges, I was going to bring the small clementines and peel them ahead of time so I don't have to worry about the peels. I like your recipe for gorp too. Thanks for sharing.

As the mom, I want to make sure that I'm as prepared as I can be and that I keep my kids and me safe. Thanks again for your detailed response to my inquiry.
