POLLEN ANALYSIS AT 5DT271, WESTERN COLORADO (1987)
Four pollen samples were analyzed from 5DT271, a multicomponent site located on the North Fork near Paonia, Colorado. This site is located in colluvium, which appears to represent displaced Pleistocene glacial deposits (Baker, personal communication, February 1987). The site exhibits three archaeological components, which have yielded radiocarbon ages of AD 1910, AD 750, and AD 10. Pollen samples were collected to observe the paleoenvironment, and possibly provide data concerning the...
POLLEN ANALYSIS AT TWO SITES IN SAND WASH BASIN, SMF1827 AND SMF1818 (1985)

POLLEN ANALYSIS, PHYTOLITH ANALYSIS, AND RADIOCARBON DATING OF CHARCOAL FROM TUMULUS SEDIMENTS, LA REVIVE, FRANCE (2005)
Pollen and phytolith analysis of two samples from a tumulus at La Revive, France, raised questions concerning the interpretation of the sediments and reproducibility of results. In an attempt to answer specific questions, three additional samples were submitted for pollen and phytolith analysis during 2005. These three samples also were floated to recover charcoal fragments that were AMS radiocarbon dated. Specific questions included dating Strata 4, 8, and 9. Stratum 4 might have been a...
