We report here the first domesticated amaranth (Amaranthus spp.) seeds to be identified at a Chacoan great house, from the northern New Mexico site known as Aztec North, where they were found in a context that dates to the mid to late twelfth century AD. Amaranth has long been recognized as an important prehispanic resource in this region, evidenced by the archaeological record of both wild and domesticated forms and by the traditional knowledge and practices of Indigenous communities. Wild amaranth and similar-appearing chenopod/goosefoot (Chenopodium spp.) seeds are routinely found in Ancestral Puebloan contexts. Recent archaeological testing at the Aztec North great house, a Chaco Canyon outlier associated with a post-Chacoan political center, has revealed the presence of uncharred domesticated amaranth seeds in a thin layer of ashy trash in a room at the rear of the great house. These seeds expand our understanding of domesticated amaranth in the American Southwest and suggest centuries of continuity of traditional amaranth cultivation within Puebloan communities.

我们在这里报告了第一批在查科恩大宅中发现的驯化苋菜（Amaranthus spp.）种子，该房屋来自新墨西哥州北部的阿兹特克北部遗址，在那里发现它们的背景可以追溯到公元 12 世纪中后期. 苋菜长期以来一直被认为是该地区重要的前西班牙资源，野生和驯化形式的考古记录以及土著社区的传统知识和做法都证明了这一点。野苋菜和外观相似的藜属/鹅足属（藜属spp.) 种子通常在祖先普韦布洛语境中发现。最近在阿兹特克北部大宅（与后查科时代政治中心相关的查科峡谷异常值）的考古测试表明，在大宅后部的一个房间内的一层薄薄的灰烬垃圾中存在未烧焦的驯化苋菜种子。这些种子扩大了我们对美国西南部驯化苋菜的理解，并表明了普韦布洛社区内传统苋菜种植的几个世纪的连续性。
