POLLEN ANALYSIS AT ARCHAEOLOGICAL THREE SITES (5LA6568, 5LA6592, AND 5LA9595) IN THE PINON CANYON MANEUVER SITE, SOUTHEASTERN COLORADO

Twenty-one pollen samples were examined from three sites in Welsh Canyon within the Pinon Canyon Maneuver Site in southwestern Colorado. A stratigraphic record was examined at the Piggyback Site (5LA6568) to provide information to compare with previous paleoenvironmental studies at the Sue Site (5LA5255) and a playa (Scott 1984), as well as geomorphic interpretations of paleoclimate (Schuldenrein 1985). Groundstone was abundant at some of the sites in Welsh Canyon. One hearth fill and six groundstone washes and associated sediment control samples were examined to provide information on plant processing by occupants of the Piggyback Site (5LA6568), the Shaft Abrader Site (5LA6592), and the Midden Site (5LA6595).
