Modern archaeological analyses and discoveries have suggested that the local native economy, which was based on women processing acorns by mortar and pestle, [6] and first observed by the Spanish upon their arrival in Central California, may have developed during the Mostin Culture period (ca. 8500 BP–6300 BP) in the Clear Lake Basin.
This action consists of a horizontal grinding motion that differs from the vertical crushing motion used in a mortar and pestle. The depth of the bowl varies, though they are typically not deeper than those of a mortar; deeper metate bowls indicate either a longer period of use or greater degree of activity (i.e., economic specialization).
