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.

While it was once believed that agriculture and pottery developed concurrently in prehistoric societies, modern research has concluded that agriculture preceded pottery making, since a sedentary life with greater food production led to both the need and time to create storage containers. Bruce Huckell has been at the forefront of a movement in Arizona archaeology that has greatly modified our understanding of the transition from the Archaic to the agricultural periods in the Southwest. Work done by Huckell and others at Matty Canyon has produced the most detailed account available of a Late Archaic village and has been extremely influential in suggesting that the cultivation of maize predated the appearance of pottery. Of Marshes and Maize presents archaeological information obtained from small-scale investigations at two deeply buried preceramic sites in the Cienega Creek Basin. Its report on excavations at the Donaldson Site and at Los Ojitos offers a thorough description of archaeological features and artifacts, floral and faunal remains, and their geological and chronological contexts. From this data, the author concludes that a major shift toward a sedentary lifeway dependent on maize agriculture had already occurred by Late Archaic times (c. 500 to 800 B.C.), demonstrating that previous research on late preceramic sites in this region has provided an inadequate picture of the period. This monograph represents the first full presentation in the literature of an important set of data that is well-known among researchers but has thus far not been easily accessible. It is a classic example of the use of fragmentary evidence in well-dated contexts to introduce new ideas, and will stand not only as an important record of the evidence but also as the primary reference for this significant new interpretation of the late Archaic and the introduction of agriculture into the Southwest.
