I agree with most everything, except a couple of points:
—these were not “experienced survivalists”; they may have gone hunting many times in TN, but experienced folks would much more completely have assessed and mitigated risk.
—SK could not be seen from the camp where he set out, even in broad daylight. That point is demonstrated simply by the inability to find him with aerial search, though the terrain looks like it’s a blank. Plus, locals appreciate how hard it is to find people. And yes, he was evidently in camo. Since he was done hunting, he and his buddy might easily have put on fluorescent orange vests if they were committed to their outfits: a very simple precaution.
An important visibility factor: the area is prone to fog.
If I look at backcountry cases where injured/lost folks are described as “experienced”, generally that’s by friends and family. It often means something like, “they’ve gone backcountry hiking/hunting/skiing/snowmobiling a bunch of times.” But this isn’t a measure of experience: it’s the luck of the draw. Most of the time, nothing will go wrong… But when your luck quotient is spent, and you haven’t assessed your real risks and prepared for them….Often, what we see missing are basics, outdoor skills 101, and not anything that would take years to learn.
