Description A whole hand-held grinding stone, also known as a pestle in Southern California archaeology. It is used in association with a grinding mortar. This multi-facial stone is used with two hands for grinding and pounding. It is flared and bell-shaped in construction, with one end twice as wide as the other. The stone material is a sandstone with inclusions of a darker stone in the interior where it is broken. It is fine grained.

The dorsal side of the stone appears to be pecked. The ventral side of the piece is flat and shows abrasion. There is also a crack and a fracture with a loss at the narrow end on the ventral side. This looks like an impact fracture that may have caused the break. The stone is mostly whole. The narrow end of the stone is 1.5 inches (4 centimeters) across and the wider base is 3.5 inches (9 centimeters) in width. This grinding or milling stone base, ventral side and on each of the sides along the length, show abrasion and usewear. Usewear marks overall suggest both flat grinding and pounding. The stone appears to be pecked on the dorsal surface and at the narrow end; pecking increases the grinding surface for greater traction.
