Low Frequency Temperature Variability And Native American Horticulture In The Northern Southwest And Eastern Great Basin, James R. Allison

Faculty Publications

Recent paleoclimatic studies reconstruct low-frequency variability in temperature that may have affected the success of Native American horticulture. Potential effects of this temperature variability include shifts in the range of elevations within which horticulture was viable, and changes in the northern limits of horticulture- based economies. This paper examines radiocarbon dates and other chronological data from Fremont and Puebloan sites in Utah, eastern Nevada, and northwestern Arizona, comparing the low-frequency temperature reconstructions with the timing of expansion and contraction in the northern frontier of maize horticulture and temporal shifts in the elevations of farming settlements.
