Description A rectangular, whole portable grinding stone platform with a depression, also known as a basin metate. The color is a reddish gray and the material is granitic (granite or granodiorite, possibly) including muscovite mica, iron oxide, with an inclusion in the basin of yellow quartz. It has a central basin that was formed by undulating, back and forth, grinding movements typically with a hand-held grinding stone, called a mano.

This grinding or milling stone's ventral platform is a polished depression, the basin, that is 11 inches (28 cm) long, 9 inches (22.9 cm) wide and 1.89 inches (4.81cm) deep. Construction of the stone created a circular angled basin, with a rough surface and may have a fragmented end with about an eighth of the total surface missing. The dorsal side of the stone is curved with two flat areas on the sloping base measuring 8 inches (20.4 cm) by 9 inches (22.9 cm). Iron oxide is leaching in some areas.
