Way to Rainy Mountain

1. I would think that one of the reasons, if there is more than one, is for Momaday to preserve the story telling tradition and attempt to put it into written words, thus reaching more people and sharing the Kiowas tradition. IN his preface, he writes that in the beginning was the word and it was spoken. He writes about reading it outloud and I think it is indeed very interesting to read silently the book and then read it out loud as a story.
2. What are the materials from which the book is constructed, and from where do they originate.I understand that the stories, materials constructing the book are from his father and the voice of Kiowa oral tradition, another of the materials come from history and historic recollections, and the other materials come from the author and his recollection, thoughts, experiences.
