In several cases rock art manufacturers were intrigued by natural rock features such as holes and cracks. This paper deals mainly with rock art images of masks that are folded across two rock panels creating 3D masks. In particular the Mogollon 3D masks of Three Rivers in New Mexico, USA, will be discussed. Also the puzzling anomaly regarding the distribution of Mogollon 3D masks and Rio Grande Style 3D masks will be dealt with. Finally, it will be attempted to offer an explanation for the enigmatic 3D masks (PDF available).
