Object Name Mano

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 shouldered by usewear. It is rectangular in shape. The stone material is a granitic with muscovite mica. It is coarse grained.

This grinding or milling stone's ventral side is rough with some polish. Its dorsal side is smooth, polished and rounded. There is a 2-inch (5 cm) long fragment missing on one end adjacent to the dorsal side and a smaller, 1-inch (2.5 cm) loss on one side adjacent to the ventral side. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. The perimeter sides and ends are squared and shouldered due to usewear. The stone appears to be pecked on the grinding surfaces; pecking increases the grinding surface for greater traction.
