Palynological study of 18 samples, including 5 associated with Archaic Period radiocarbon dates and 1 associated with Fremont Culture artifacts, identifies a pollen sequence for the site. The inferred paleoclimatic sequence fully agrees with dated sequences from central New Mexico and the Llano Estacado.
Complacent pollen records associated with both extinct fauna and archaeological remains argues that Southwest has been semi-arid throughout Late- and Post-Pleistocene.
This study of 23 pollen samples allows recognition of a sequence of ecosystem changes occurring in central New Mexico between A.D. 1280 and 1400 and also in the 1650 - 1750 period. It also discusses the effects of such changes on aboriginal maize agriculture. Draft of the report included in Archaeological Excavations at Pueblo del Encierro.
Pilot study of 9 pollen samples to assess pollen preservation, potential to aid stratigraphic analysis, and recognition of environmental changes.
