The single spiral is the symbol of Ho-bo-bo, the twister who manifests his power by the whirlwind. The myth explains that a stranger came among the people, when a great whirlwind blew all the vegetation from the surface of the earth and all the water from its courses. With a flint, he caught these symbols upon a rock, the etching of which is now in Keam's Canyon. It is 17 inches long and 8 inches across. He told them he was the keeper of the breath.The whirlwind and the air which men breathe come from this keeper's mouth. The spiral also symbolized a way of planting, starting at the center and moving out in circles as they planted.
In Navajo it was called ha'oolmaaz.
