There are two large mounds comprised of enormous quantities of construction debris and discarded household debris associated with rapid growth of the Pueblo Bonito great house in Chaco Canyon between ca. CE 1040 and 1100. There is some debate among specialists as to whether these features were expedient refuse middens or constructed platform mounds or something in between, and thus whether they index political processes linked to control of labor by elites. Although originally investigated by archaeologists between 1896 and 1927, this study presents the first detailed formation history for each mound, based on recent fieldwork by the University of New Mexico. We argue that the mounds were not the product of institutionalized political power as assumed for platform mounds in other parts of North America but rather reflect local landscape changes associated with complex social negotiations during a period of rapid social transformation.

有两个大土墩由大量的建筑垃圾和废弃的家庭垃圾组成，这些垃圾与大约在 2000 年之间的查科峡谷的 Pueblo Bonito 大房子的快速增长有关。CE 1040 和 1100。专家之间存在一些争论，即这些特征是权宜的垃圾堆还是建造的平台土墩或介于两者之间的东西，因此它们是否索引与精英控制劳动力相关的政治进程。尽管最初由考古学家在 1896 年至 1927 年间进行调查，但这项研究根据新墨西哥大学最近的实地调查，首次展示了每个土墩的详细形成历史。
