Poor chronology has long plagued the Patayan archaeological tradition of the far-western reaches of the North American Southwest. Archaeologists typically rely upon ceramics to assign associated materials to the broadly defined Patayan I, II, and III periods. However, as data amass, it is becoming increasingly clear that the established date ranges for certain types of Patayan pottery tied to those periods are inaccurate, and that the overall chronology may benefit from revision. Consequently, there are renewed calls to reassess the ceramic typologies and identify attributes with utility for dating affiliated archaeological phenomena. Here I focus on one such attribute, the stucco surface treatment on Lower Colorado Buff Ware. While the prevailing typology regards stucco as diagnostic of the Patayan II and III periods (circa AD 1000–1900), I present data that show stucco is conspicuously absent from contexts dating before AD 1400 but is rather common thereafter. I conclude Lowland Patayan potters began applying stucco to their wares between 1400 and 1600, and this attribute is therefore useful for dating associated material to a narrower AD 1400–1900 timeframe.

时间差的年代早已困扰着北美西南部遥远地区的Patayan考古传统。考古学家通常依靠陶瓷为广泛定义的Patayan I，II和III时期分配相关材料。但是，随着数据的积累，越来越明显的是，与这些时期相关的某些类型的Patayan陶器的既定日期范围是不准确的，并且总体年表可能会从修订中受益。因此，人们再次呼吁重新评估陶瓷的类型，并确定具有实用性的属性，以便对相关的考古现象进行测年。在这里，我重点介绍一种这样的属性，即Lower Colorado Buff Ware上的灰泥表面处理。尽管流行的类型学认为灰泥可以诊断出Patayan II和III时期（大约在公元1000-1900年），我提供的数据表明，灰泥在公元1400年之前的情境中明显缺失，但在此之后却相当普遍。我得出结论说，低地Patayan陶工开始在其1400至1600年间将灰泥应用于他们的商品，因此该属性可用于将相关材料的日期追溯到更窄的AD 1400-1900时间范围。
