|'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 or two hands for grinding and was shaped in construction. It is rectangular in shape. The stone material is a sandstone, mainly composed of quartz. It is coarse-grained and sub-rounded. It is a burned rock.
This grinding or milling stone's ventral and dorsal sides are well worn, smooth and stained dark. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. The stone appears to be pecked on the perimeters; pecking increases the grinding surface for greater traction.
