On what real life event is the novel, The Man to Send Rainclouds, based?

The story is based on an incident Silko had heard about in her hometown of Laguna, New Mexico: an old man had been found dead in a sheep camp and had been given a traditional Indian burial. The local Catholic priest resented the fact that he had not been called in to officiate at the service. Silko's story explores the Indians' blending of Catholic rituals with traditional Indian rituals during a funeral ceremony. The tension of maintaining traditional Pueblo practices and the co-opting of outside influences—in this case, the Catholic church—is a recurring interest of Silko's and appears in several of her stories.
