10 minutes before the end of the film, Hope and Dalglish find Dillon lying chest down in the snow, with his arms at his sides. They turn Dillon over on his back, and his frozen arms are still at his sides. In the next camera shot, Dillon's hands are on his chest, holding a set of rosary beads.
Near the end of the film, Donald and Francis arrive back to town on horseback. Several men are walking behind them. Two men in Russian style hats are wearing modern day aviator sunglasses.
Around the 1:43 mark when the prospector is torching the town we see a ski lift running in the background with people on it. Again around the 1:54 mark in the last few minutes of the film we see the ski lift again in the background for a good 10-15 seconds.
