|'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 oval in shape. The stone material is a sandstone with muscovite mica. It is coarse grained and porous.
This grinding or milling stone ventral side is polished from grinding and has a large dark stain. Its dorsal side is also polished from grinding. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. There is texture on the perimeter sides; it is not conclusive that they were used in grinding. The stone appears to be pecked or porous on the ventral and dorsal surfaces due to the nature of the stone, rather than pecking that is deliberately applied to increase the grinding surface for greater traction.
