Casa Grande Ruins酒店位于亚利桑那州中南部的索诺兰沙漠，靠近柯立芝。废墟代表了Hohokam（古索诺兰沙漠）人民的农业社区，这是一个由中美洲影响文化的早期农民建造的村庄，在300至1450年之间蓬勃发展。废墟被命名的“大宅”是村庄的后期建筑，是一座建于公元1350年的四层11室建筑，是北美有史以来最大的史前建筑之一。它由粘土，粘土，沙子和碳酸钙的天然组合构成，混合成泥浆稠度然后用作建筑材料 – 干燥时很难像混凝土一样。这个结构可能是一个住所，一个寺庙或一个天文观测台 – 没有人真正知道它的目的是什么。早在大房子建成之前，随着人口的增加，沿着沙漠河流的生活变得难以维持，人们开始在公元400-500左右建造灌溉渠。吉拉河周围有数百英里的史前灌溉渠，以及凤凰城的盐河和图森的圣克鲁斯河，这使得人们可以在山谷外种植玉米，豆类，南瓜，棉花和烟草。
Casa Grande Ruins is located in the Sonoran Desert in south-central Arizona, close to Coolidge. The ruins represent the agricultural community of the Hohokam (the ancient Sonoran Desert), a village built by early farmers of Central American influence culture, flourishing between 300 and 1450. The ruins named “The Mansion” is the late building of the village. It is a four-storey 11-room building built in 1350 AD and is one of the largest prehistoric buildings in North America. It consists of a natural combination of clay, clay, sand and calcium carbonate, mixed into a slurry consistency and then used as a building material – difficult to dry like concrete. This structure may be a residence, a temple or an astronomical observatory – no one really knows what its purpose is. As early as the completion of the big house, as the population increased, life along the desert river became difficult to maintain, and people began to build irrigation canals around 400-500 AD. There are hundreds of miles of prehistoric irrigation canals around the Gila River, as well as the Salt River in Phoenix and the Santa Cruz River in Tucson, which allows people to grow corn, beans, pumpkin, cotton and tobacco outside the valley.
