Object Name Mano
'Iipay Aa Name hapiichaa
Description 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 mostly volcanic cobble, likely granitic with gold (weathered biotite) mica. It is medium grained.

This grinding or milling stone ventral side is polished with some recent scarring noted by the lighter color compared to darker and older abrasions. The dorsal side is polished with some abrasion, vertical scratches. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement on both sides. The small surface area of the stone suggests some finer grinding, perhaps medicinal or pigment rather than food processing.
