|'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 or possibly two-hand for grinding and was shaped in construction; it is somewhat shouldered by usewear. It is rectangular in shape. The stone material is granitic with biotite mica. It is coarse grained.
This grinding or milling stone's ventral side is flattened, polished, and pecked; pecking increases the grinding surface for greater traction. Its dorsal side is rounded and smooth. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. It is an unusual loaf-shaped object and may be two-handed in size.
