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 quartzite with muscovite mica. It is medium grained.

This grinding or milling stone ventral side is smooth and pecked; appears dry and dull. This grinding stone dorsal side is polished and slightly pecked. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Worn marks on the perimeter sides indicate some use. The stone appears to be pecked on all surfaces; pecking increases the grinding surface for greater traction.
