POLLEN, STARCH, AND MACROFLORAL ANALYSIS AT DEEP CREEK PARK SITE #1, 24CA1009, CENTRAL MONTANA

Soil samples from cultural fill in five test units at Site 24CA1009 in Deep Creek Park,
Montana, were floated to recover charred macrofloral remains. Three samples from Unit 4 also
were examined for pollen. This site is situated around a spring and has previously documented
prehistoric cultural use. Charred material from Level 2 of Unit 4 yielded a calibrated radiocarbon
date of 2310-1955 BC (Beta-81033), which is derived from a conventional C14 age of 3740 +
60 BP. Pollen and macrofloral analyses are used to provide information concerning plant
resources that may have been used by the prehistoric occupants of the site.

蒙大拿州深溪公园（Deep Creek Park）24CA1009遗址的5个探方（test units）的文化堆积（cultural fill）土样，经浮选法回收炭化大植物遗存（charred macrofloral remains）。此外，对第4探方的3份土样开展了孢粉分析（pollen analysis）。该遗址紧邻泉水分布，此前已确认存在史前人类活动遗存。第4探方第2层的炭化物质经校正放射性碳测年（calibrated radiocarbon date）得到结果为公元前2310-1955年（编号：Beta-81033），该测年结果基于常规碳14年龄（conventional C14 age）3740±60 BP（Before Present）。本次孢粉分析与大植物遗存分析，旨在为了解该遗址史前居民可能利用的植物资源提供相关信息。
