Show Figure 15.2. Graphic representation of the utility of radiocarbon dating for the Puebloan period, which increases with age but is virtually nil after about 1050 AD (more recent than ca. 960 BP); shown are 1) the radiocarbon calibration curve (atmospheric data from Reimer et al [2004] as graphed by OxCal v3.10 [Bronk Ramsey 2005]), highlighting portions that are flat and exhibit marked reversals, 2) ceramic-defined temporal periods for the northern Kayenta region, and 3) Christenson's (1994:307) point of demarcation for markedly different accuracies in mean ceramic dates (MCDs).
