From the Navaho, The Wanderings

The Maiden from the Water Buffalo's Kingdom became a mother and a grandmother. There were many people counted as her descendants. They planted corn in the canyon where they lived, and their corn ripened, having tassels and bearing rich ears.

One day the people sent a boy and a girl down into the canyon. Suddenly they looked down and saw a flood coming from above. They called to the children, but the flood carried them away, leaving the cornfields unharmed. These two children were taken back to the home of the great Water Buffalo.
