Archeology of Sivu'ovi: The Archaic to Basketmaker Transition at Petrified ForestNational Park

摘要

During 1989 and 1990, a small-scale excavations were conducted at Sivu'ovi (ASQ:1:114 ASM), Petrified Forest National Park, Arizona. Sivu'ovi is a large (12 acre) Basketmaker II site that includes the remains of over 45 pit structures. Also within the site boundary, but not tested as part of the current fieldwork, are several small field houses that date to a later Pueblo period occupation. The site contains an abundance of artifacts on the surface, including Adamana Brown pottery, the earliest identified ware in the region. Chronometric data indicate a pre-A.D. 300 date for occupation at Sivu'ovi and the Flattop Site, perhaps indicate a pre-A.D. 300 date for occupation at Sivu'ovi and the Flattop Site, perhaps as early as 300 B.C. at Sivu'ovi. However, occupation from A.D. 1 to 200 may be the best estimate at this time for the Basketmaker II occupation at both sites. These are the earliest dates yet for sites with ceramics in the middle Little Colorado River region. In both respects Sivu'ovi appears to be transitional between the Archaic and Pueblo periods. Testing confirmed that Sivu'ovi contains abundant and varied data, and further work at the site is recommended to mitigate the effects of continued erosion and to realize more of the site's information potential.
