About infrasound: In the modern world, it is an everyday environmental nuisance that many of us are exposed to on a daily basis. Engines (car, train, ship...) produce infrasound, so does road traffic, electric transformers, airplanes, construction work, and so on. Not to mention industry. It can be annoying but if it caused insanity or panic, there would be many cases worldwide. And there are none. There are people who report hearing (sensing) "the hum" and being annoyed by it, but they also don't describe it as a panic, but a persistent annoyance. It wakes them up at night, or prevents them falling asleep, and can compel them to walk around looking for the source, instead of resting. But they don't run from their houses without their coat or shoes...
About the wolverine:
I agree that it is a compelling theory, more so than most. But there are still too many unlikely things we need to assume: All the searchers must have missed the wolverine prints leading to and from the tent (they describe not finding any animal prints in the area), the wolverine's liquid must have sublimated completely, otherwise the investigator and his colleagues, and anyone who has been in the same building as the tent was kept and examined, must have smelt it, as it melted (I assume it was frozen in/on the tent fabric and the tent's contents, but must have melted at room temperature); the same applies to relatives who received the clothes of the victims; and finally we must assume that the wolverine risked entering the tent for the food there, but then didn't take it, and didn't return for it for a month, even though the tent was empty and there was no threat to it any more.I think in conclusion that if a wolverine caused them to leave the tent, the evidence we're left with would look different: no loin left in the tent, and at least some trace smell still detectable, for example by the ranger who took part in the search, and possibly other things like for example at least one hiker throwing up outside the tent.. and possibly some surviving because after all, all they needed to do is go to the forest, make a fire which they did, warm up a bit, take a long enough branch and fish out their coats etc from the tent, wash them in the stream and dry them by the fire.
