When Bryson and Katz arrive on foot at "the bunkhouse" the next day after the snowstorm, the camp is covered in snow but the surrounding trees and foliage are totally devoid of snow.

I had just started watching during this scene and the trees are not only devoid of snow, the background trees were deciduous and in full summer foliage stage in the background.
I think this film was made for profit and nobody cared about the work. Film is supposed to be an artform. If you're going to push the film out like a fart why even bother in the first place.
