Etched pebble recovered from Feature 13 at Arroyo de la Presa, a large trash pit dated to the middle portion of the Late Prehistoric period (A.D. 1040-1260). The artifact was shaped by natural stream rolling, but the etched or incised lines were added. Such artifacts may have functioned as talismans or charms, the specific meanings of which are lost to time. Photo by Andy Cloud. |
