A Sequence of Interbedded Cultural and Natural Deposits at Point of Pines, Arizona

ABSTRACT Post-Pleistocene alluvial sequences on the Colorado Plateau and in the Sonoran Desert have been studied since the early 1920s. This paper documents a sequence of alluvial and cultural deposits from the intervening mountainous region at Point of Pines in east-central Arizona. Four periods of channel cutting have been identified. The earliest channel is poorly known, but the interbedding of well-dated cultural layers with fluvial deposits permits precise dating of the second channel to the final decades of the thirteenth century and good correlation with the Tsegi-Naha erosional episode on the plateau. The third channel postdates a.d. 1450, and the fourth is the active channel of the present-day stream. The geomorphic, hydrologic, fluvial, climatic, and human factors in the Point of Pines region need to be more thoroughly studied before this alluvial sequence can be fully interpreted.
