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 and is a pale brown in color. The stone material is Granodiorite. It is medium to course grained.

This grinding or milling stone's ventral side is smooth and flat with some pecking; pecking increases the grinding surface for greater traction. Its dorsal side is smoother and slightly rounded. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. The perimeter sides are rough.
