Having disturbed one of them, she is pursued only to be rescued from them by her ex-husband, Andrew.
Police believe the family died of carbon monoxide poisoning after the heating system inside the cabin suffered a massive failure.
The Coconino County Sheriff's Office said the family had not been heard from in several days and concerned relatives asked an officer to carry out a welfare check.
Footage showed children's toys over the floor of the cabin, as well as overnight bags with the family's clothes.
The first responders eventually found the bodies of the four family members.
The heating unit was the only gas appliance in the home.
