Corrected entry: The whole film is stupid. If they had stayed where they were, in an open area, to be seen easily, and with, say, 3/4 fires burning, to keep the bears (and other creatures) away and as signal fires, and near the water, so they can drink it and, with all of the above, they would have been found in 1/2 days. But then they wouldn't have a film, would they?

Correction: The whole point of moving was to find a more likely search area. As it was, they were 20 miles away from where anyone thought they'd be. After that, they were being chased by the bear and did what they had to do to survive long enough to be found, regardless of where it took them.
