|'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 shouldered by usewear. It is square in shape. The stone material is a granitic, leucocratic plagiogranite with muscovite mica. It is fine grained.
This grinding or milling stone's ventral side is heavily pecked and grooved; pecking increases the grinding surface for greater traction. Its dorsal side is smooth and polished. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Wear marks on the perimeter sides are squared from use.
