Zuni and Hopi Kachina dolls are representations of spiritual beings. The Hopi of Northeastern Arizona carve the root of the cottonwood to create kachina dolls. There are hundreds of different kachina dances practiced by the Hopi. The Zuni Kachina Cult is one of the six major cults of Zuni. A more recent etymology is that Kokopelli means literally "kachina hump". The Zuni Kachina Cult is not constant, it changes to space and time. Voth and Warburg saw a Hemis Kachina dance complete with obscene clowning. During Kachina ceremonies, each child receives their own doll. The Kachina Doll Ranch was a supervised play area for guests' children. Another snapshot is of Warburg wearing a Kachina dancer' s mask. Around 1325 CE Kachina masks and Kachina dancers appear as rock art. Spider Grandmother and kachina spirits figure prominently in some myths. Other Native American peoples also relate kachina spirits to heavy snowfalls on the peaks. Their second and subtle role is in the sacred kachina rituals. Some folklore legends say that the Kachina figure, "Chakwaina," is based on Estevanico.
