This closer look shows some cut lines to control water use by leading to the next hole below the ones above. Carving rocks is not common in this area.

This fact was considered to a curse on the women who prepared the daily acorn meal, and that was a main staple food. The acorn mush was cooked in woven baskets heated with hot rocks taken from a fire.
