The Occasional Papers of the Canyon Archaeological Center is a five-volume series published by the Center from 1989–1995. The volumes include important contributions to archaeological research by Crow Canyon staff and research associates including an influential volume on communal architecture in the Pueblo Southwest edited by Bill Lipe and Michelle Hegmon; the first series of publications from the Sand Canyon Archaeological Project; the site report for Crow Canyon’s excavations of the Duckfoot Site—one of the most thoroughly documented Pueblo I occupations in the Four Corners region—and Ricky Lightfoot’s authoritative doctoral dissertation on household archaeology at Duckfoot; and Michelle Hegmon’s highly influential doctoral dissertation connecting pottery style to social dynamics at local and regional scales across the Pueblo Southwest. Starting with The Sand Canyon Archaeological Project: Site Testing report in 1999, Crow Canyon archaeological reports began to be published in digital format and the Occasional Papers series ended.
