|'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 rectangular in shape and shouldered. The stone material is granitic with gold (weathered biotite) mica. It is medium grained.
This grinding or milling stone ventral side is highly polished with a large chip out of one corner, flattened and shouldered. Its dorsal side is stained, smooth and slightly pecked; pecking increases the grinding surface for greater traction. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement.
