Excavations At 29SJ627, Chaco Canyon, New Mexico: Volume I. The Architecture and Stratigraphy

Site 29SJ 627 is located on the west side of Chaco Canyon, directly opposite the Park's Visitor Center and just north of the Chaco and Fajada (Vicenti) wash confluence (Figures 1.1-1.3). The site is situated in the middle of an alluvial plain in an area referred to as Marcia's Rincon, bounded on the west by South Mesa and limited on the north and south by two, low, unnamed ridges (Figure 1.4).

During the Chaco Project's 1974 and 1975 excavations, 25 rooms, portions of seven pit structures, several plaza areas, and trash accumulations were disclosed, indicating at least 350 to 400 years of occupation. Site use, although perhaps not continuous or of consistent intensity, lasted from the middle to late A.D. 700s to the early to middle A.D. 1100s with architectural and ceramic indications of limited A.D. 600s habitation. The period of most intensive site use was from the late A.D. 800s through the middle A.D. 1000s.
