Wendigo - (Part of my 100 Monsters series)
"Many legends and stories have circulated over the years about a mysterious creature who was encountered by hunters and campers in the shadowy forests of the upper regions of Minnesota. In one variation of the story, the creature could only be seen if it faced the witness head-on, because it was so thin that it could not be seen from the side. The spirit was said to have a voracious appetite for human flesh." - Ghosts of the Prairie
