A total of 283 botanic samples were submitted for analysis from 21 sites located in Yellowhouse Draw and Yellowhouse Canyon, Lubbock, Texas. The area is geologically stratified with five primary strata, four buried substrata, and one surface soil. Samples were recovered from stratigraphic sediments, although the sampling method is not known. It is generally accepted that for plant remains from prehistoric archaeological sites or stratigraphic deposits to be preserved, they must be carbonized. Samples submitted for analysis were retrieved from trenches, features, or areas. Only seeds and/or charcoal were received for botanical analysis, rather than entire samples. Charred and uncharred seeds and charcoal were identified.本次研究共提交283份植物样本用于分析，样本采集自美国德克萨斯州拉伯克市黄豪斯冲沟（Yellowhouse Draw）与黄豪斯峡谷（Yellowhouse Canyon）区域内的21处考古遗址。该区域地质分层清晰，包含5套原生地层、4套埋藏下伏地层与1套表层土壤。尽管采样方法尚未明确，但所有样本均发掘自地层沉积物中。学界普遍认为，史前考古遗址或地层沉积中的植物遗存若要得以保存，必须经过炭化作用。本次提交分析的样本均发掘自探沟、遗迹或相关区域，且仅接收了种子与/或炭屑（charcoal）用于植物考古分析，而非完整样本。研究人员对炭化与非炭化种子及炭屑进行了鉴定。
