Much of what he did sounded sensible to me. He stayed and rested at Clapp Spring until night, and then travelled in the dark. He also informed a friend that he was in difficulty, and told him to raise the alarm if they didn't hear from him the next morning. They did so promptly (S&R found his tracks early the next morning) - the comment in the other thread about unreliable friends waiting for two days doesn't match the new report.

The body was difficult to find, so I wonder if he got lost in the night and ended up trying to travel during the morning. If so, then a GPS might have saved him. He was only 1.2 miles from his camp. I think his decision-making ability must have deteriorated rapidly leading him to make some bad choices towards the end.
