For over a century, archaeologists have investigated the vast network of prehistoric Hohokam canal irrigation systems in the lower Salt River and middle Gila River valleys, as well as in other areas of southern Arizona. However, documentation of the agricultural fields in which prehistoric farmers irrigated their crops generally was lacking until the last 25 years. This is largely a result of the difficulty in identifying ancient fields, since they are not visible on the surface and have been obscured or destroyed by natural landscape processes as well as historic and modern disturbances. More recent archaeological investigations have revealed ancient irrigated fields through innovative methods and excavation techniques. The fields were constructed both by Hohokam irrigators (450–1450 CE) as well as by farmers from preceding cultural traditions during the Early Agricultural period (2100 BCE–50 CE). These discoveries occurred during projects conducted in compliance with the National Historic Preservation Act. In this chapter, I highlight these important studies that have expanded the view of ancient agricultural landscapes in southern Arizona. [ABSTRACT FROM AUTHOR]

Much of what is known regarding Historic period Native American communities is based on studying documents that were written by non-indigenous peoples. However, archaeological excavations in a portion of the Blackwater Village within the Gila River Indian Community provide another perspective on Native American life ways within south-central Arizona during the late 1800s. The latter nineteenth century was a pivotal time for the Akimel O'Odham (i.e., Pima) who have long lived within the Phoenix Basin, and they experienced dramatic changes in their subsistence strategies, settlement patterns, craft production, and other cultural practices during this time. These recent investigations demonstrate that the Akimel O'Odham were not passive recipients of Euroamerican culture, and instead they chose to adopt some aspects of non-native practices while at the same time retaining important traditions. As a result, the Akimel O'Odham have successfully maintained their society in the face of tremendous hardships, and Blackwater Village remains a vibrant settlement to this day. [ABSTRACT FROM AUTHOR]
