|'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 two hands for grinding and was shaped in construction; it is shouldered by usewear. It is rectangular and loaf-shaped. The stone material is granitic with muscovite mica. It is medium grained.
This grinding or milling stone ventral side is flattened and smooth. This grinding stone dorsal side is smooth and humped. 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 indicate some shouldering from use. The stone appears to be lightly pecked on the ventral surface; pecking increases the grinding surface for greater traction.
