|'Iipay Aa Name||hapiichaa|
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 unshaped in construction. It is oval in shape. The stone material is a granitic (granite) with gold (weathered biotite) mica and inclusions of biotite. It is very coarse grained.
This grinding or milling stone ventral side is slightly flat from grinding and lighter color. This grinding stone dorsal side is pecked, rounder and darker; pecking increases the grinding surface for greater traction. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Wear marks on the ends indicate battering and ends are fractured from use.
