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 rectangular in shape and reddish brown in color. The stone material is sandstone with quartz and is subrounded. It is medium to course grained.

This grinding or milling stone's 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 surface on both sides. The edges of the mano are rougher and porous.
