I'itoi
Iʼitoi or Iʼithi is, in the cosmology of the O'odham peoples, the mischievous creator god who resides in a cave below the peak of Baboquivari Mountain, a sacred place within the territory of the Tohono O'odham Nation. O'odham oral history describes I'itoi bringing Hohokam people to this earth from the underworld. Hohokam are ancestors of both the Tohono O'odham and the Akimel O'odham ( River People). He is also responsible for the gift of the Himdag, a series of commandments guiding people to remain in balance with the world and interact with it as intended.
Visitors to the cave are asked to bring a gift to ensure their safe return from the depths.
