POLLEN ANALYSIS AT A TEMPORARY CAMPSITE IN THE LA PLATA VALLEY, NEW MEXICO

A lithic scatter (DCA-85-184) in the La Plata Valley, San Juan County,
New Mexico, represents a temporary camp. This archaeological site was
sampled for pollen in four areas during archaeological testing. Based on
projectile point morphology, the occupation of the site appears to fall
within the Basketmaker II or III time periods. A single large roasting
pit/hearth was recovered and sampled for pollen. In addition, pollen samples
were taken from artifact clusters at the site. Pollen sampling was
structured to recover subsistence data from this site, as well as to identify
the environment at the time of occupation.

新墨西哥州圣胡安县拉普拉塔谷内的DCA-85-184号石制品散布点（lithic scatter）为一处临时营地遗址。该考古遗址在考古勘探期间于四个区域开展了花粉采样工作。根据投射尖状器的形态特征，该遗址的人类居住活动年代可归入筐篮文化（Basketmaker）二期或三期时段。研究人员还发现了一处大型烘烤坑/灶址，并对其进行了花粉采样。除此之外，还从遗址内的人工制品聚集区采集了花粉样本。本次花粉采样方案的设计目标，一是从该遗址获取生计相关数据，二是明确该遗址人类占据时期的古环境状况。
