The House of the Cylinder Jars details the archaeological excavations led by Patricia L. Crown at Pueblo Bonito’s famed Room 28 in Chaco Canyon in 2013. Originally excavated in 1896 by the Hyde Exploring Expedition, Room 28 gained notoriety for its incredible assemblage of 174 whole ceramic vessels. Crown and her team reopened Room 28 after she and Jeffrey Hurst discovered residues of chocolate in cylinder jar fragments from Pueblo Bonito in 2009. Their research revealed the first evidence of chocolate north of the US-Mexico border and possibly linked Chacoan rituals surrounding cacao use to Mesoamerica. The House of the Cylinder Jars documents the re-excavation of Room 28, and places it within the context of other rooms at Pueblo Bonito, and describes the ritual termination by fire of the materials stored in the room. The contributors also offer a modern interpretation of the construction and depositional histories of surrounding spaces at Pueblo Bonito in Chaco Canyon.
