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 or two hands for grinding and was shaped in construction. It is rectanguloid in shape. The stone material is a sandstone with muscovite mica. It is fine grained.

This grinding or milling stone's ventral side is pitted and has a white residue or growth. Its dorsal side is smooth with an 3/4 inch (2 cm) area of black smudge, perhaps tar. Striations appearing on the surface suggest that this mano was used in an undulating movement. Wear marks on the perimeter sides suggest some grinding. The stone appears to be pecked on the ventral surface; pecking increases the grinding surface for greater traction.
