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 granitic with muscovite mica. It is coarse grained.

This grinding or milling stone ventral side is flat, polished and pecked. The grinding stone dorsal side is humped, polished and pecked. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. The perimeter sides are somewhat shouldered and one end shows grinding polish. The stone appears to be pecked on the surfaces; pecking increases the grinding surface for greater traction.
