@unsung: the meals will be fine for your trip. I wouldn’t store them for any period of time repackaged, but no issues for your trip.
FWIW, expect hazy skies and a smoky smell during your loop. I got back from the Sawtooths a week ago, and we definitely could smell the fire burning on an adjacent mountain range at times. Even had small bits of ash fall on us a couple of times during our hike.
In the below pic it’s smoky skies causing that wonderful orangish, red glow. The brighter glow is the sun going down.
