When Wacey is asked if they can make it to the elk camp on foot before sundown he holds four fingers up to the sky. This is a way of gauging how many hours it is to sunset. Each finger width the sun is above the horizon equals approx 15 mins.
When young Joe opens the Christmas present from his dad in the beginning of the episode, it is a left handed .22 bolt rifle and young Joe holds it like a left handed shooter would. Later in the episode they show the gun again and it is now a right handed .22 bolt gun and young Joe holds it as a right handed shooter.
