Results of the Phase II Geoarchaeologic Field Investigations, Kirtland Air Force Base, Bernalillo County, New Mexico

Summary

The results of this preliminary study indicate that arroyos in this region have been quite dynamic in the Holocene and this activity has resulted in a significant archaeological visibility bias. Rapid sedimentation rates (0.3 to 0.66 cm/year) and thick alluvial fills demonstrate that large volumes of sediment have been repeatedly mobilized in brief periods of time in the past. The discovery of several buried Archaic archaeological sites in the arroyo deposits suggests that the lack of known sites in the arroyo valley floors may simply be an artifact of visibility. The identification of Holocene age eolian and alluvial fan deposits suggests that significant portions of the base ( e.g. the piedmont), not examined in detail during this study, may have significant visibility problems. The results of this brief field investigation clearly demonstrate that geologic processes have had a profound influence on the discovery and inventory of archaeological sites in arroyo and some alluvial fan settings, and that the dynamic nature of these portions of the landscape should be considered when evaluating their archaeological potential.
