A summed probability density function (spdf), generated from the catalog of 101 radiocarbon ages on wood and charcoal from the Čḯxwicən archaeological site (Washington State, USA), serves as a proxy for the site's occupational history over the last 2500 years. Significant differences between spdfs derived from a null model of population growth (a bootstrapped logistic equation) and the observed index suggest relatively less cultural activity at Čḯxwicən between about 1950–1750 cal BP, 1150–950 cal BP, and 650 to 550 cal BP; and increased activity between about 1350–1250 cal BP and 550–500 cal BP. Peaks in the Čḯxwicən spdf are closely …
