Alaska has seen from press things just how pudgy people have gotten. There will be far more deaths if they keep trying to get these portly people to walk that distance.

The real bus, where he actually stayed, was in another area of Denali, which would have told him that it had been driven there [update to original post: I read the book and learned that the real bus was one of three junked, undrivable buses that were "sledded" there by Caterpillar tractors and meant to serve as refuges or base camps for hunters; rest of original post stands]. So there had to be a safe way out, and when he saw the raging river river and thought he was trapped, he should have looked for a safer crossing, which did exist about a half mile away. If he'd had a decent map of the area (he didn't), he would have found it.
That's sad, especially brought home to me when he wrote in his diary, toward the end, something like, "Happiness is not real unless shared." It took him all that time to realize it, but it was too late.
