@5W's From observing cases involving missing hikers for a few years, you can look at a place and think there’s no chance someone’s remains could still be there because you’ve “looked everywhere” and there are no obvious hazards. Years later, someone might stumble on remains exactly there. It happens all the time.

There would be a high chance of them missing something, and they ran the risk of destroying whatever clues might be out there.
Don’t forget, SK’s clothing was intended to conceal him.
Here is a desert case in an urban setting from last weekend that you’d think would be an easy find. It used SAR and 200 volunteers (who were invited to participate by SAR). It took several days to find the body, and she had colored clothing.

So, IMO, I don’t think we can judge a find likelihood by appearances. There are so many factors at the AK site that make it very likely SK is on the ground and very unlikely he’d be found.
