Object Name Mano

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. The stone material is a sandstone (sedimentary) with muscovite mica. It is fine grained.

This grinding or milling stone ventral side is flat and smooth. This grinding stone dorsal side is less 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 suggest light or no use. The stone appears to have a naturally pecked surface due to the quality of the material; pecking increases the grinding surface for greater traction.
