Ground Stone Analysis: Summer 2009

The analysis of the groundstone has focused only on the materials from Creswell Pueblo this summer.  The analysis examines the grinding surface of atool and it’s shape. 

Below are a few artifacts that have been particularly interesting from Structure 2 at Creswell Pueblo.  We started with this structure because it had a large groundstone assemblage in it.  We don’t know why but area also investigating this question. 

This first object is a portion of a mano that had broken off prehistorically.  Manos were used (and are still used today) along with metates in order to process food such as corn.  You can see where the ancient people who used the mano decided to recycle the object by creating a circular depression on the top.

The picture below is a small pestle made of volcanic rock that was used to crush and grind.

This is a piece sandstone that has been shaped into a circle.  We don’t know exactly what it was used for, maybe a lid for sealing an ancient pot.
