But they also entered the supernatural and used its powers to cure, make rain, control animals, find lost objects, predict the future and sometimes bewitch their enemies.
Supernatural power was called poha. A shaman was known as a pohagunt, or "man having power". Rock art sites were among the most powerful of the ritual locations used by shamans. They were called pohaghani, or "house of power".
Petroglyphs were made at the conclusion of the shaman's vision quest, immediately after he came out of his trance. This vision quest involved isolation from other people, fasting, meditation and sometimes, the use of tobacco. All of these activities can result in hallucinations, which were considered to be sacred visions.
