What's new in Chaco research?

This special section of Antiquity reports on new research on Chaco Canyon and its surrounding region in the northern U.S. Southwest. Two of the contributions are based on new excavations within Chaco Canyon-one at the largest great house of Pueblo Bonito by Patricia Crown and W.H. Wills (2018), and the other on Chaco's water management by Vernon Scarborough et al. (2018). The second pair of articles are based on the regional data compilation and analyses of great houses and great kivas, which form part of the larger Chaco World. The article by Mills et al. (2018) applies social network analysis to a large database of ceramics to look at changing connectivity in the Chaco World over three centuries. Katherine Dungan et al. (2018) use an innovative total viewshed approach to examine when and to what degree great houses and great kivas were placed in visually prominent locations. This introduction reviews new findings of the past decade and contextualises the following four articles within the current literature. It does not provide a comprehensive review of the Chaco literature, and the reader is referred to other reviews, most recently by Plog (2010, 2018), Schachner (2015) and Plog et al. (2017). These can be compared with earlier syntheses (Mills 2002; Lekson 2006, 2009) to underscore the pace of new research.
