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 sandstone with quartz. It is medium-grained and angular to rounded.

This grinding or milling stone ventral and dorsal sides are smooth. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Construction of the stone created a smooth yet porous surface on the sides. The stone is wider on one end and is noted in laboratory notes as being "odd shaped."
