Description A whole hand-held grinding stone, also known as a mano in Southern California archaeology. This bifacial stone is used with one hand for grinding and was shaped in construction. It is rectangular in shape. The stone material is fine-grained quartzite with an orange-brown cortex and lighter color in abraded areas.

This grinding or milling stone ventral side is polished with some staining, oily perhaps from use. This grinding stone dorsal side is polished. One end shows the orange cortex fading or abraded, and there is a large chip in the end. Striations appearing on the surface suggest that this mano was used in an undulating or back and forth movement. Wear marks on the perimeter sides includes some shouldering and slight battering from use.
