The occurrence of nonlocal objects, raw materials, and ideas in the southwestern United States (U.S. SW) has long been recognized as evidence of interaction between prehispanic peoples of this region and those of greater Mesoamerica. Although many archaeologists have analyzed the directionality and potential means by which these objects and concepts moved across the landscape, few have assessed the degree to which Mesoamerican practices and traditional assemblages remained intact as the artifacts and ideas moved farther from their places of origin. The current study analyzes the distribution and deposition of blue-green stone mosaics, a craft technology that was well established in Mesoamerica by the Late Preclassic period (300 BC–AD 250) and spread to the U.S. SW by the start of the Hohokam Pioneer period (AD 475). We assess the spatial distribution, contextual deposition, and morphology of mosaics at sites within Hohokam Canal System 2, located in the Phoenix Basin of Arizona. We use these data to infer mosaics’ social value and function within Hohokam social structure. Analyses suggest that, although the technology of mosaic making may have originated in Mesoamerica, the contexts and ways in which mosaics were used in the Hohokam regional system were decidedly Hohokam.

美国西南部 (US SW) 出现的非本地物品、原材料和思想长期以来一直被认为是该地区前西班牙裔人民与大中美洲人民之间相互作用的证据。尽管许多考古学家分析了这些物体和概念在景观中移动的方向性和潜在方式，但很少有人评估过中美洲实践和传统组合随着文物和思想远离其起源地而保持完好的程度。目前的研究分析了蓝绿色石头马赛克的分布和沉积，这是一种工艺技术，在前古典时期晚期（公元前 300 年至公元 250 年）在中美洲建立起来，并在霍霍坎先驱时期开始时传播到美国西南部（公元 475 年）。我们评估了位于亚利桑那州凤凰盆地的 Hohokam 运河系统 2 内站点的马赛克的空间分布、背景沉积和形态。我们使用这些数据来推断马赛克在 Hohokam 社会结构中的社会价值和功能。分析表明，虽然马赛克制作技术可能起源于中美洲，但在霍霍坎地区系统中使用马赛克的背景和方式无疑是霍霍坎。
