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 quartzite. It is medium grained.

This grinding or milling stone ventral side is polished with some pecking; a large flake is missing at one end. This grinding stone dorsal side is heavily pecked with some polish. There are flakes removed from the center. Pecking increases the grinding surface for greater traction. 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 use.
