A flat, rectangular, whole, portable grinding stone platform, also known as a metate. The stone material is a granitic (granodiorite, leucocratic) with both biotite and muscovite mica indicating a somewhat higher level of radioactivity. It is medium grained. It has a central grinding surface that was formed by rotary grinding movements typically with a hand-held grinding stone, called a mano.
This grinding or milling stone's ventral platform is polished for an area that is 12.4 inches (31.75 cm) long and 7 inches (18 cm) wide. Construction of the stone created a flat rectangular surface that slopes vertically. The dorsal side of the stone is a flatter, wedgelike base.
