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 is shouldered in usewear. It is circular in shape. The stone material is granitic with muscovite mica. It is coarse grained.
This grinding or milling stone ventral side is heavily pecked, flattened with some polish. This grinding stone's dorsal side is rounded, polished and slightly pecked. Pecking increases the grinding surface for greater traction. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Wear on the perimeter sides show shouldering from heavy use.
