|“||Anasazi symbols. It's for protection. The Wendigo can't cross over.||”|
There were several Anasazi symbols and many used circles and curved lines. Many appeared to draw inspiration from natural objects like the sun or what appeared to be humans.
Dean drew several of these symbols around their campsite, implying that drawing a lone symbol would not stop a wendigo, and that several of the symbols must be used together in order to enclose an area safe from the monster, not unlike how one would create a ring of salt or goofer dust. As Dean created the symbols simply by sketching them on the ground, Anasazi symbols appeared effective regardless of how they were drawn.
