摘要 北太平洋海岸是了解人类在美洲殖民的重要地区，但晚更新世海岸遗址十分罕见，间冰期海平面上升淹没了大陆架和古海岸考古遗址可能出现的主要区域。在这里，我们概述了一个陆地考古调查项目，旨在识别加利福尼亚州圣罗莎岛的古海岸遗址。通过对古代海岸线和古地理的重建，我们预测可能会发现石器资源、淡水泉、洞穴或岩石庇护所以及战略景观吸引古沿海人民进入岛屿内陆的地点。我们确定了 9 个新的古海岸地点，其中包括 4 个放射性碳，其年代 > 11,000 cal b.p.。它们是北美太平洋沿岸最古老的遗址之一。我们的针对性调查展示了调查岛屿和沿海环境的重要技术，在这些环境中，海平面上升仍然是定位早期地点的重大挑战。
Abstract The northern Pacific Coast is an important area for understanding human colonization of the Americas, but Late Pleistocene coastal sites are rare and interglacial sea level rise has inundated the continental shelf and the primary areas where Paleocoastal archaeological sites are likely to occur. Here we outline a terrestrial archaeological survey project designed to identify Paleocoastal sites on Santa Rosa Island, California. Using reconstructions of ancient shorelines and paleogeography, we predicted that sites might be found where lithic resources, freshwater springs, caves or rockshelters, and strategic vistas drew Paleocoastal peoples into the island interior. We identified nine new Paleocoastal sites, including four radiocarbon dated to >11,000 cal b.p. that are among the oldest sites on North America’s Pacific coast. Our targeted survey demonstrates an important technique for investigating island and coastal settings where sea level rise remains a significant challenge for locating early sites.
