Volume One of a Two-Volume Set. The ASM Archaeological Series is a scholarly, peer-reviewed, monograph series focused on the archaeology of Northwest Mexico and Southwest U.S.

This volume describes the archaeological investigations and syntheses of research that William Self Associates, Inc. (WSA), conducted at the Marsh Station Road site, an extensive, multi-component, semi-permanent habitation site with occupations spanning the Early Agricultural period through the Hohokam Classic period and located southeast of Tucson.

In the 1960s and 1970s, Arizona Archaeological and Historical Society volunteers, University of Arizona students, and Pima College stu-dents excavated Whiptail Ruin, a mid- to late- AD 1200s village in the northeastern Tucson Basin. This volume presents the results of anal-yses of the notes and artifacts from work at that site.
