A sipapu (a Hopi word) was a small hole or indentation in the floor of a kiva (pithouse).
The sipapu symbolizes the portal through which their ancient ancestors first emerged to enter the present world.
[1] Hopi mythology (and similar traditions in other Pueblo cultures such as the Zuni and Acoma) states that this is the hole from which the first peoples of this world entered.
The original sipapu is said in Hopi and some other Uto-Aztecan Puebloan mythology to be located in the Grand Canyon.
