description: In August, 1990, archaeologists from Desert Archaeology, Inc. monitored the excavation of a water pipeline trench through the northeastern edge of a multiple-occupation archaeological site sitting upon and buried within an alluvial fan at the western edge of the Santa Cruz River terrace. Several prehistoric cultural features in a buried occupation horizon were identified. Mesquite wood charcoal from the floor of a pithouse yielded a conventional radiocarbon date of 3040 ± 1 1 0 B.P. (radiocarbon years before A.D. 1950), confirming a Late Archaic date for this phase of site occupation. Charred maize cupules and kernels identified in samples of sediment from the pithouse floor represent, therefore, new evidence of the earliest phase of agricultural settlement along the river valleys of the Sonoran Desert.
