ABSTRACT In the mid-twentieth century, excavations at the Buena Vista Lake site (CA-KER-116) in the southern San Joaquin Valley of California resulted in the identification of a deposit dating from the early Holocene characterized as a San Dieguito variant. This deposit contained several fragmentary points, crescents, faunal remains, and large features consisting of processed freshwater bivalves. Since the 1960s, the Buena Vista Lake site was the sole well-dated example of human occupation in the region during the early Holocene. However, similar materials have recently been identified at the Buttonwillow site (CA-KER-2720) and comparable materials are also known at Tulare Lake. These three examples appear to form a coherent pattern of a Western Stemmed Tradition variant in the southern San Joaquin Valley, a variant proposed here as the Buttonwillow Complex.

Buttonwillow Complex：加利福尼亚州圣华金河谷南部拟议的西部茎干传统变体

摘要 在 20 世纪中叶，在加利福尼亚州南部圣华金河谷的布埃纳维斯塔湖遗址 (CA-KER-116) 的挖掘中发现了一个可以追溯到全新世早期的矿床，该矿床的特征是圣迪吉托变体。该矿床包含几个零碎的点、新月形、动物群遗迹和由加工过的淡水双壳类动物组成的大型特征。自 1960 年代以来，布埃纳维斯塔湖遗址是该地区在全新世早期人类占领的唯一一个过时的例子。然而，最近在 Buttonwillow 站点 (CA-KER-2720) 发现了类似的材料，图莱里湖也发现了类似的材料。这三个例子似乎在圣华金山谷南部形成了一个西方词干传统变体的连贯模式，
