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 square in shape. The stone material is granitic with gold (weathered biotite) mica. It is medium grained.

This grinding or milling stone's ventral side is smooth and lightly pecked. Its dorsal side is 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 are shaped and squared with use; there is some fragmenting on the dorsal side ends. The stone appears to be lightly pecked on the side and ventral surfaces; pecking increases the grinding surface for greater traction.
