I've believe something like the big foot or more importantly the abominable snow man for many years now.
Due to Uruguayan Air Force Flight 571, also known as the Andes flight disaster, in South America, http://en.wikipedia.org/wiki/1... this was a rugby team that crashed and survived close to two months, on a snow whipped mountain top.
The big deal about this crash is they had to eat the dead to live. The book (which I read) mentions two large "ape like creatures were that were "busy" in the route they were taking to get down so they diverted. They tried to wait them out but grew tired of waiting so circled around them. It sounded like they ("apes") were waiting for the survivor out of curiosity.
They might of of been called abominable snow men in the book but there was no real clue what they were other than very large, ape looking beings (given bears they could of been).
