It is true they are much lighter than a human so might not leave prints in harder snow..
I have another objection... wolverines mostly eat carrion... If there was one in the area, wouldn't the corpses have bites? I have read that wolverines have special teeth so they are even able to feed on frozen meat. And also their food is most scarce in winter so they'd be desperate.
Yes they seem to eat anything. There must have been animal trails within the area as there are the Mansi hunters and they obviously to build labaz to protect their food. So animals are definitely about.
When they say were no animal prints it must just mean at the tent or animal tracks get covered or destroyed quicker?
The Wolverine would not have been hunting them but followed their smell. There is a story of a Wolverine following a man in to a snow hole and they both sat there until the blizzard passed. The man apparently held a knife at the ready.
They don't seem overly scared of humans and have poor eyesight. If the Wolverine crawled in to the already over crowded tent , I could imagine the panic.
If it sprayed it's weapon then it could explain the chaos,especially in the confined space of the tent. Apparently the smell causes nausea and dizziness to the point of almost unconscious.
There were yellow stains found on some of the clothes that would not wash off ( if I remember correctly) . Also ,this smell would probably ward of other animals eating the corpse's for the 3 weeks. I would of thought the 2 Yuri's might have suffered from scavenging.
The Wolverine that may or may not have entered the tent might have ran away after the confrontation. The group couldn't get their belongings and dumped the clothes outside the tent that were contaminated purely because of the smell that can knock you out.
I have tried to research how bad and toxic the smell can be but can't find anything scientific.
