Description A rectangular, whole portable grinding stone platform with a depression, also known as a basin metate. The color is gray with reddish areas and the material is granitic (tonalite) [perhaps from Campo, CA] including gold mica (weathered biotite mica). Iron oxide is leaching in areas of the base and appearing in several small circular concentrations in the basin. 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 or basin that is 15.5 inches (39.4 cm) long, 11 inches (28 cm) wide and .81 inch (2.6 cm) deep. Construction of the stone created an angular shaped surface. The dorsal side of the stone is curved with a flat, uneven base measuring 8.75 inches (22.5 cm) by 8 inches (20.4 cm). There are abrasions and dark earth stained areas on the base.
