Momaday had many purpose’s in writing his novel Rainy Mountain. The main purpose is to educate the public about the Kiowa tribe that lived between the 18th and 19th centuries in the United States. Although the Kiowa tribe may have been forgotten by the prodominence of the population, Momaday refuses to let the history fade away into oblivion. Another purpose to writing the novel was the loss of his Grandmother who was a Kiowa symbol to him. His Grandmother was the last of the Kiowa’s known to Momaday so writing the novel helps keep the history of the Kiowa’s alive and proves to be very important and personal to him to continue his family name and culture through the novel. Another motivation behind the novel is to teach good morals and lessons
