|'Iipay Aa Name||hapiichaa|
A whole hand-held grinding stone, also known as a mano in Southern California archaeology. This large bifacial stone is used with one hand and possibly two hands for grinding and was shaped in construction. It is oval in shape. The stone material is a granitic (granite) with muscovite mica and inclusions of pink feldspar. It is coarse grained.
This grinding or milling stone has long, fine, dark-feathered mineral lines on two areas. All sides equally pitted and appear similar. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Wear marks on the width of the perimeter sides suggest grinding. The stone appears to be pecked over the entire surface, although a bit smoother on the dorsal side; pecking increases the grinding surface for greater traction.
