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.

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.
