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 oval in shape and is a pale yellowish brown. The stone material is Sandstone with quartz grains. It is fine to course grained.

This grinding or milling stone's ventral side is pecked; pecking increased the grinding surface for greater traction. Its dorsal side is very smooth with a few areas of stone loss. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Rough on the perimeter sides. There are a number of stains on the mano.
