Describe symbolism in God Is Red: A Native View of Religion by Vine Deloria

The author does not use symbolism in the text, symbolism is, however, mentioned. In the book, we learn that the Indians used animal hide, usually from a Buffalo, to draw a symbol that illustrated the most significant event of that year. There was no real criterion for the subject matter therefore, the Winter Count does not give a complete and accurate picture of a specific time and place. A similar system was held by tribes in Arizona, who wrote symbols on a "calendar stick."
