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 and shouldered by usewear. It is oval in shape. The stone material is a granitic with biotite mica. It is coarse grained.

This grinding or milling stone ventral side is heavily pecked. The dorsal side is lightly polished and pecked. 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 mostly on ends. The stone appears to be heavily used and pecked on the most surfaces; pecking increases the grinding surface for greater traction.
