This volume describes the archaeological investigations and syntheses of research that William Self Associates, Inc. (WSA), conducted at the Marsh Station Road site (AZ EE:2:44 ASM]), an extensive, multicomponent, semi-permanent habitation site with occupations spanning from at least 3000 to 550 B.P. (1050 B.C. to A.D. 1400), from the Early Agricultural period through the Hohokam Classic period, located southeast of Tucson. The twelve chapters in this volume include detailed discussions of the cultural setting and environmental context, both past and modern, for the site, as well as of the fieldwork conducted at the site and of specialized analyses of artifacts (ceramics, flaked stone, ground stone, faunal, and shell ) and environmental samples, (macrobotanical remains and pollen) recovered from the site. These data are interpreted in order to place the Marsh Station Road site within a local and regional framework, in which the site is considered from a heartlands/hinterlands perspective as an important example of how prehistoric farmers in southern Arizona subsisted in a nonriverine landscape.
