About one hour into the movie--everyone loads their gear in the basket on the side of the helicopter and climbs in; then, as the helicopter takes off, the basket is completely empty.
Five people went up in the helicopter for avalanche training; but when they got to the top of the mountain, there were six.
When Chris and Heather are skiing down the mountain after setting up her equipment, they are skiing in fresh powder but the dog is running with them on a groomed run.
When Chris and Heather are talking on the slope after setting up her station, the equipment and/or crew are visible in the reflections on their goggles.
Nice signs for Fernie, British Columbia everywhere in the movie, with great aerial photography of The Elk River Valley also in BC, Canada. Glacier National Park in Montana, USA only a few hours away - not so much.
