Description A fragmented, portable grinding stone platform with a depression, also known as a basin metate. The material is leucocratic granitic (granodiorite, pegmatite) including muscovite mica with garnet crystal inclusions on the base. It is coarse grained. 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 forms a polished depression, the basin, and is 8.25 inches (20.95 cm) long, 10.5 inches (26.6 cm) wide and 1.3 inches (3.3 cm) deep. Construction of the stone created an uneven surface. The dorsal side of the stone is curved with a rounded, rough base. There is a streak of red weathering on one edge.
