|'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 shaped in construction. It is ovoid in shape. The stone material is a granitic (granite) with gold (weathered biotite) mica and pink feldspar. It is fire-affected and coarse grained.
This grinding or milling stone ventral side is slightly saddle-backed and is polished and pitted. This grinding stone dorsal side is polished and pitted. 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 grinding on one edge and dark fire-affected stain on another. The stone appears to be pecked on the dorsal and ventral surfaces; pecking increases the grinding surface for greater traction.
