Between Desert and River: Hohokam Settlement and Land Use in the Los Robles Community' by Christian E. Downum (1993) contains extensive information based on an archaeological survey in the Los Robles area which covers the northeast section of Ironwood Forest National Monument. From the abstract:

This monograph focuses on the results of archaeological surveys and excavations along Los Robles Wash, a desert stream_ that is tributary to the Santa Cruz River in northern Pima and southern Pinal counties, Arizona. Data from these investigations are used to reconstruct patterns of prehistoric and protohistoric settlement and land use along Los Robles Wash and to illustrate that the so-called "intermediate" areas between interior deserts and the major river valleys to the north were in fact densely settled and dynamic components of the Hohokam world.
