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 somewhat shaped in construction with little shouldering; it had some use. It is circular in shape. The stone material is a granitic (granodiorite) with muscovite mica and an area of dark rusting inclusion. It is fine grained.

This grinding or milling stone ventral side is darkened from some use. This grinding stone dorsal side is lighter and smooth. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Wear marks on the perimeter sides suggest light use except in one area. The stone appears to be lightly pecked ventral surface; pecking increases the grinding surface for greater traction.
