|'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 circular in shape. The stone material is a granitic (granite) with muscovite mica and pink feldspar. It is medium grained.
This grinding or milling stone ventral side is heavily used with dark staining and some debris. This grinding stone dorsal side is dark in part 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 suggest light use and there is no shouldering present. The stone appears to be pecked on the ventral surface; pecking increases the grinding surface for greater traction.
