|'Iipay Aa Name||hapiichaa|
A whole hand-held grinding stone, also known as a mano in Southern California archaeology. This bifacial stone is used with one hand for grinding and was shaped in construction. It is oval in shape. The stone material is granitic with muscovite mica. It is medium grained.
This grinding or milling stone ventral side is flat, polished and slightly pecked; it is stained brown from use-wear. This grinding stone dorsal side is polished and slightly saddled. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Wear marks appear on one perimeter end. The stone appears to be pecked on the ventral surface and one end; pecking increases the grinding surface for greater traction.
