本文调查了更新世晚期东部五大湖的湖平面变化，以深入了解早期古印第安人的职业。提供了有关湖平面历史的重要新信息，特别是在ca现代以上的高水位的第一个有据可查的沉积物。11，000 - 10，300 B. P.时期在休伦湖盆地南部。湖平面信息，结合古环境和现场资料，沿着估算了11000年前的碳酸盐岩年龄;表明大量遗址已被水位上升淹没;提供了关于考古遗址设置的具体信息，如将帕克希尔遗址置于一个大型湖泊河口附近;指出海岸线对古印第安人具有吸引力的原因，包括持续存在的更开阔的区域有利于更高的游戏生产力;并指出了未来考古遗址调查的理想区域，特别是在伊利湖流域。John Wiley & Sons，Inc.
This article investigates changing lake levels in the late Pleistocene eastern Great Lakes inorder to gain insights into the Early Palaeo-Indian occupations. Significant new informationbearing on lake level history is provided, notably the first well-documented deposits of a highwater level above modern in the ca. 11,000–10,300 B.P. period in the southern Lake Huronbasin. The lake level information, along with paleoenvironmental and site data, reinforcessite age estimates to the 11th millennium B.P.; suggests significant numbers of sites have beeninundated by rising water levels; provides specific informationonthe settingofarchaeologicalsites such as placing the Parkhill site adjacent to a large lake estuary; indicates reasons forthe attractiveness of shorelines to Palaeo-Indians including persistence of more open areasconducive to higher game productivity; and points to ideal areas for future archaeologicalsite survey, particularly in the Lake Erie drainage. 2000 John Wiley & Sons, Inc.
