The novel Hollow Mountain: Celestial Fire by Tibetan writer Alai and The Way to Rainy Mountain by Native American writer Navarre Scott Momaday are both classics in minority literature. From the perspective of ecological writing, this article employs Lu Shuyuan’s tripartite division theory to examine the natural, social, and spiritual ecological crises in the two works. In terms of natural ecology, the Tibetan people’s view of “the unity of gods and humans”, the Kiowa’s sun worship and natural beliefs are fading. In terms of social ecology, certain positions in Tibetan society are erased, but traditional culture is maintained, while the Kiowa’s oral tradition disappears with the passing of generations and the spread of English. In terms of spiritual ecology, both the Tibetan people and the Kiowa have experienced processes of collapse and recovery, with the former embracing reform while obtaining spiritual revival, and the latter emphasizing a retrace to historical memory.
