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 shouldered but not shaped in construction. It is circular in shape. The stone material is a sandstone (sedimentary) with gold biotite mica. It is fine grained.

This grinding or milling stone ventral side is smooth with a small hole created by a crystal falling out. This grinding stone dorsal side is somewhat smooth with a whitish weathering or leaching. 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 some grinding and there is also whitish weathering or leaching. The stone appears to be lightly pecked on the surface; pecking increases the grinding surface for greater traction.
