Object Name Mano
'Iipay Aa Name hapiichaa
Description 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 ovoid in shape. The stone material is a sandstone (sedimentary) with muscovite mica. It is fine grained.

This grinding or milling stone ventral side is rough. This grinding stone 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 suggest grinding, especially on each end. The stone appears to be pecked on the ventral and perimeter surfaces; pecking increases the grinding surface for greater traction.
