two water bottles, you get so dyhdrated so fast when you're up at the glaciar.
dark lenses, for the sun, remember it's summer so the sun is gonna be super bright.
hoodies and t shirts, it gets really warm there and you won't wanna be wearing a jacket.
sunscreen, i didn't wear it when i went and i got the worst sunburn on my face that ive ever gotten in my life.
Those are the four things that when i got back from camp, i thought, "oh shit i should have brought them."
