“In Mexican cosmology the sky fell down as a result of profound rainy spell. Two gods changed themselves into trees with which it was then supported. Rain also caused the collapse of the sky in a story told by the {{w|Cahto|Kato}} of the northwestern United States. {{w|Cahto#Religion|Naga-itcho, Great Traveler}}, saw that the old sky which was made of {{w|sandstone}} and badly cracked in places was about to fall, so he and Thunder constructed a new sky.”
