A rectangular, fragmented, portable grinding stone platform with a depression, also known as a basin metate. The shaped metate is a gray with red areas and the material is granitic (granodiorite) including muscovite mica. Some areas of red iron oxide are leaching through. It has a central basin that was formed by rotary grinding movements typically with a hand-held grinding stone, called a mano. There may have been recent grinding in the basin since there is a powdery gray substance, very loose on the surface.
This grinding or milling stone's ventral platform has a polished depression; the basin is 9 inches (23.0 cm) long, 7 inches wide (17.8 cm) and 3/4 inch (2.0 cm) deep. The dorsal side of the stone is curved with rough sides and appears to have a burned area (fire-affected) or soil mark around the perimeter base. It also has a missing fragmented end and a deep gouge (2" x 3.5 inches) at the other end on the same side. The flat area on the base measures 11.5 inches (29.4 cm) x 3.5 inches (9 cm).
