Diné Bahane? (Navajo: "Story of the People"), is the Navajo creation story, and involves 4 worlds. The First World was small and centered on an island floating in a the middle of four seas, the Second World was inhabited by various blue-gray furred mammals and various birds, the Third World had 2 rivers that formed a cross and the Sacred Mountains but no sun, and the Fourth World was covered in water, with monsters (naayéé?) living there.
