Water Baby footprint petroglyphs in the Owens Valley. The dark, desert varnish (patina) on the surface of the rock has been carefully chipped away to reveal the lighter material underneath that forms the designs. The Paiute and Shoshonean peoples in this part of the Owens Valley, report hearing Water Baby (pau' ha) writing on the rocks himself. He is a diminutive spirit helper who acts as a particularly potent helper to shamans. The sight of his tracks signifies a supernatural experience.
