POLLEN AND PHYTOLITH ANALYSIS FOR SITE 41KR621, TEXAS

Site 41KR621 is located within the boundaries of a proposed right-of-way extension
along Spur 98 in Kerrville, Texas. Situated on the southern approach of Spur 98 to the
Guadalupe River, this multi-component, Mid to Late Holocene prehistoric site covers the entire
highway right-of-way from the base of an upland toeslope at the southern terminus to the scarp
of a terrace above the river. Soil matrix samples from several features at the site were
examined for pollen and phytoliths, as were samples from a stratigraphic column from units
CT 3 and CS 3. Pollen and phytolith analyses are used to provide a backdrop of information
concerning local vegetation and the paleoenvironment, as well as information concerning plant
resources available to and utilized by the prehistoric occupants of site 41KR621 , which is
believed to have experienced Early, Middle and Late Archaic occupations.

41KR621号遗址位于美国得克萨斯州克尔维尔市98号支线（Spur 98）拟建道路通行权扩建范围之内。该遗址地处98号支线通往瓜达卢佩河（Guadalupe River）的南侧引道区域，是一处多遗存组合的全新世中晚期史前遗址，其分布覆盖整条高速公路通行权用地，北起南端尽头的高地坡麓基部，南至河上方阶地的陡崖地带。研究人员对遗址内多处遗迹的土壤基质样本开展了孢粉与植硅体分析，同时对地层单元CT 3与CS 3的地层柱样本进行了相同检测。孢粉与植硅体分析旨在为当地古植被与古环境背景提供数据支撑，同时可揭示41KR621号史前遗址先民可获取并加以利用的植物资源相关信息。经推断，该遗址曾存在早、中、晚阿恰特（Archaic）文化阶段的人类活动遗存。
