Unktehi, a water monster, fought the people and caused a great
flood. The people retreated to a hill, but the water swept over
them, killing them all.
Unktehi was turned to stone; her bones are in the Badlands
now. A giant eagle, Wanblee Galeshka, swept down, saved one girl
from the flood, and made her his wife. (In another version, the
thunderbirds fought and defeated Unktehi and her children before
the waters washed over the highest mountain.)
