This account of Classic Period settlement in the Tucson Basin between A.D. 1100 and 1300 is the first comprehensive description of the organization of territory, subsistence, and society in a Hohokam community of an outlying region. Broad recovery of settlement patterns reveals in unique detail the developmental history of the Marana Community and its hierarchical structure about a central site with a platform mound. Remains of diverse agricultural technologies demonstrate the means for supporting populations of previously unrecognized size.
