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 oval in shape. The stone material is a granitic with gold (weathered biotite) mica. It is coarse grained.

This grinding or milling stone ventral side is heavily used, pecked, polished and oil stained in one corner. Its dorsal side shows lighter use with some pecking and polish. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. The perimeter sides and ends show some use. The stone appears to be pecked on the surfaces; pecking increases the grinding surface for greater traction.
