|'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 squarish in shape. The stone material is granitic with muscovite mica. It is medium grained.
This grinding or milling stone's ventral side is smooth and polished. Its dorsal side is polished and pecked. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. The perimeter sides are smooth and shaped; one end is rough and perhaps used as a hammer. The stone appears to be pecked on one surface; pecking increases the grinding surface for greater traction.
