Thanks. Interesting that everything seems to have been in his backpack. Seems that with his backpack as a starting point, a K9 could have tracked him - maybe not, canine sensors are not magic. How about one of those UAV thingamajigs (that’s a real word btw) with an IR/Thermal sensor - more magic.

A little pocket carry goes a long way. This goes to the EDC is always changing... thread. Going for a walk without my backpack, maybe take some stuff (call it insurance) along just in case. A small knife, a small flashlight, a whistle, a signal mirror, one of those ubiquitous (unless you’re hiking by yourself off trail) cellphones could go a long way to getting yourself out of a self-induced problem.
