Research background The close of the thirteenth century A.D. marked the end of permanent residential occupation in large portions of the Ancestral Pueblo world (Adler, 1996). Broadly speaking, this demographic event reshaped the configuration, cultural composition, and perhaps even religious practices of communities throughout the northern US Southwest (Adams and Duff, 2004; Duff, 2002; Spielmann, 1998; Van Keuren and Glowacki, 2011). By the early 1300s, local populations and migrant groups coalesced into plaza- oriented villages, many of which were organized spatially into loose settlement clusters (Adams and Duff, 2004). Fourmile Ruin was among five villages in the Silver Creek cluster, east-central Arizona (Fig. 1)(Kaldahl et al., 2004; Mills, 1998). This site and others in the cluster are perhaps best known for their production of figurative-style pottery (Fourmile Polychrome) by the 1320s (Carlson, 1970: 71), which may have been associated with new religious beliefs that spread across the Pueblo world (Adams, 1991, 1994; Hays-Gilpin and LeBlanc, 2007). 2.1. Fourmile Ruin in context Fourmile Ruin was first recorded by archaeologists more than a century ago (Fewkes, 1904; Spier, 1919). Jesse Walter Fewkes excavated portions of the site during a two-week expedition in Fig. 1.

Based on the presence of well-dated Fourmile Ruin to illustrate how ritual closure can be inferred using ceramic types (Carlson, 1970; Mills and Herr, 1999), the site was stratigraphic evidence and geoarchaeological observations of the first established by the end of the 1200s, and then expanded constituent sediments. Our work builds on recent studies of ritual sometime in the early- to mid-1300s. Permanent residential deposits in the Ancestral Pueblo Southwest, namely work in the occupation by Pueblo peoples ended in the area during the final Middle Colorado River Valley to the north (Fig. 1). Here, Walker and decades of the 1300s (Mills, 1998). his colleagues (Adams and LaMotta, 2006; Walker, 1995; Walker Fourmile Ruin was subject to several episodes of systematic et al., 2000) have examined the ritual closure of structures at looting prior to its transfer from a private landowner to The thirteenth- and fourteenth-century villages in the Homol’ovi Archaeological Conservancy. Although the contents of rooms were region. Adams and LaMotta (2006:60e62) discuss the nature of cleaned out, the resulting architectural remains provided a wealth of “enriched deposits” in religious structures (including kivas) at information on wall construction sequences and materials.
