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 was shouldered by usewear. It is squared in shape. The stone material is quartzite with rust-colored and brownish inclusions. It is medium grained.

This grinding or milling stone ventral side is polished and rounded. This grinding stone dorsal side is rough with a small area of polish. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Worn marks on the perimeter ends show battering and grinding usewear. The stone appears to be pecked on the perimeter and possibly the dorsal surface; pecking increases the grinding surface for greater traction.
