POLLEN ANALYSIS FROM NATURAL CHIMNEY ROCK SHELTER (SJC-1548), NEW MEXICO

Three pollen samples were collected for analysis from Natural Chimney
Rock Shelter (SJC-1548). Prehistoric use of this site probably encompasses
BM III to P I and possibly P II time periods. Three groundstone fragments
were recorded at the site. Two prehistoric and one modern feature were also
noted at the site. All appear to be firepits, as they contained varying
quantities of charcoal and fire-reddened sandstone. The two prehistoric
features were sampled for pollen, and a third sample was collected from the
soil beneath an inverted slab metate. Pollen analysis was oriented toward
the identification of subsistence activity at the site.

研究从天然烟囱岩庇护所（Natural Chimney Rock Shelter，编号SJC-1548）中采集了三份花粉样本以供分析。该遗址的史前使用时段大致涵盖BM III至PI时期，或许还包括P II时期。遗址内共记录到三件研磨石器碎片，此外还发现两处史前遗迹与一处近现代遗迹。上述遗迹均疑似火塘，其内留存有数量不等的炭屑与火烧变红的砂岩。两处史前遗迹均采集了花粉样本，另外还从一块倒置石板磨盘下方的土壤中采集了第三份花粉样本。本次花粉分析旨在识别该遗址的生业活动情况。
