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 circular in shape. The stone material is volcanic, perhaps basalt. It is coarse grained.

This grinding or milling stone ventral side is pecked and polished. This grinding stone dorsal side is pecked, polished and chipped. 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 and ends indicate battering. The stone appears to be pecked overall increasing the grinding surface for greater traction.
