Object Name Mano
Description A whole hand-held grinding stone, also known as a mano in Southern California archaeology. Due to qualities of usewear, it may also be a multi-use, mano-pestle. This multifacial stone may be used with one hand for grinding and two hands for pounding. It was shaped in construction; it is shouldered by usewear, particularly on one end. It is rectangular and loaf-shaped. The stone material is a granitic with muscovite mica. It is medium grained.

This grinding or milling stone ventral side is polished and flattened. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. This grinding stone's dorsal side is rounded and lightly pecked on one side near to an end that may be a pestle end. Wear marks on this particular end are flattened and there is some abrasion or pecking in a semicircle on the dorsal side.This may indicate the stone striking the side of a stone bowl or mortar, as a pestle. The stone is longer and larger than many manos in this collection.
