Description A whole, flat, rectangular shaped grinding stone platform with a depression, also known as a basin metate. It is heavy, but perhaps still portable. The color is a tan with reddish flecks and the material is granitic (granite) including calcite, feldspar and deep red garnet stone inclusions of a glossy hardness. It has a central basin that was formed by rotary 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, 5.5 inches (14 cm) wide and .25 inch (.063 cm) deep. Construction of the stone created a shaped and rough surface. The dorsal side of the stone is curved with a flat base measuring 10.5 inches (26.8 cm) long by 5 inches (12.7 cm) wide. The rock is exfoliating on the ventral surface perhaps due to exposure. The remainder of the rock is stable.

Length - 16.850", Width - 9.212", Height - 4.251", Weight - 40 lbs.
