More than 5000 rock structure sites are found in northeastern United States, but their cultural attribution has long been debated. Some argue than many are prehistoric in origin, while others maintain they all date to colonial times. Few have been dated, and of those that have, the association of the dated material and the rocks can be challenged. Here, we provide luminescence analysis on the rocks themselves at a large site in eastern Pennsylvania. Our results suggest an age coeval with the Adena culture of the Ohio Valley.

宾夕法尼亚州东部一个可能的美洲原住民石碑和墙壁遗址的光学刺激发光测年

在美国东北部发现了 5000 多个岩石结构遗址，但它们的文化归属长期以来一直存在争议。有些人认为许多起源于史前，而另一些人则认为它们都可以追溯到殖民时代。很少有人已经过年代，而在那些已经过时的材料和岩石的关联中，可以受到挑战。在这里，我们提供了宾夕法尼亚州东部一个大型地点的岩石本身的发光分析。我们的结果表明与俄亥俄河谷的阿德纳文化同时代。
