Encounters of Wendigos

The first in the "Scary Stories to Tell in the Dark" books has an entry on the Wendigo.

Also, and don't read this unless you want to become angry enough to go on a rampage and kill everyone you know, but the absolutely ridiculous Jack Chick, who makes those little fanatical religious comic books you find in phone booths and at the doctor's office, released a series of books by a guy named William Schnoebelen, who claims to have been a Satanic High Priest, even though not a thing he says is in any way truthful and is derived from the Satanic Scare of the 1980's. He has a three-book series, "Blood on the Doorpost," "Lucifer Dethroned," and "Wicca." In Lucifer Dethroned, he talks about seeing a gigantic wendigo that blocked out the stars as a child.

Personally, I believe I've encountered Wendigo, way up in the mountains of West Virginia in one of the harshest winters I can recall. No hard evidence, but I was with a small group of people and we all were 100% sure that the wind was talking to us in a very unpleasant way.
