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 a rectangular wedge in shape with very flat faces. The stone material is a granodiorite with feldspar, hornblende, biotite mica with a trace of quartz. It is fine to medium grained.

This grinding or milling stone's ventral and dorsal sides are flat, it has two opposite working surfaces that have worn the stone into a slight wedge. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. There are worn marks on the perimeter sides and some areas of loss.
