In the Land of Lava: Petrographic and Chemical Analysis of Pottery from El Malpais National Monument

Summary

Pottery found at four sites located in the eastern half of El Malpais National Monument offers significant clues into the importance of this area for the southern Chaco cultural extension. Further, the movement of pottery within the area is also significant as is information on local or non-local production. In order to begin to understand these issues, chemical and petrographic analysis was carried out on pottery mostly from the great house site of Las Ventanas. The Cibola White Ware, Socorro White Ware and White Mountain Red Ware are dominated by sherd temper that can cause difficulties for analysis. This may have resulted in the many chemical groups identified, for which petrography indicated some connections. We suggest that Cibola White Ware from the monument was made at many sites, while Socorro White Ware and White Mountain Red Ware may have had more limited production. Examination of the NAA data within a larger database also indicated such a pattern. These results have provided a preliminary hypothesis on pottery exchange in this area which further analyses will test.
