Some have surmised they were headed back to the highway after camping at Cold Lake Municipal Campground the night before, which makes sense, since they got stuck about 10 am that morning. The campground is in the upper left corner:Thank you very much for this. I tried to find this location a while back, and could not.
It makes me wonder what on earth they were doing there? The only thing I can think of is looking at the back of the houses, maybe seeking an unoccupied one (or worse) or a car to steal.
