Before the Pima Animal Care Center (PACC) was expanded recently its parking lots and outbuildings partly covered a unique piece of the prehistoric Hoho-kam landscape. Ancient settlement at PACC can be divided into two distinct episodes: The Tortolita phase (ca. AD 570-670) occupation, which corresponds with the founding of Hohokam villages throughout southern and central Arizona, and the Late Rincon/Tanque Verde (ca. A.D. 1150-1250) occupation that occurred during the transition between the Hohokam pre-Classic and Classic periods.

Environmental constraints combined with the ex-isting social landscape likely led to the abandonment of the Tortolita habitation at PACC, but not the place.

Investments made in the land and the rights to those lands remained tied to the social group who moved from PACC. Evidence suggests the floodplain adjacent to PACC continued to be farmed long after habitation at PACC ceased.

As pre-Classic villages began to fragment in the eleventh and twelfth centuries, people returned to the abandoned settlement at PACC, drawn by their long-held ties to the land. New habitation structures were constructed within the old plaza, which was the physical and social center of the abandoned village.

Though not "occupied" for 450 years, archaeo-logical evidence shows the rights to the farmlands associated with the place had been maintained through

time. During a time of social stress, the holders of those rights, real or created, returned.

For the March 2019 "Third Thursday Food for Thought" dinner, archaeologist Dr. Michael Lindeman will discuss and illustrate the excavations at PACC by archaeologists from Desert Archaeology, Inc., that led to this interpretation of long-term Hohokam use of the landscape.

Guest presenter Michael Lindeman, Ph.D., began his professional archaeological career 30 years ago working in the eastern United States (New York and South Carolina). He also worked in Germany and Central America before focusing on the southwestern United States. Dr. Lindeman has 25 years of experience conducting archaeological fieldwork and research throughout Arizona, Colorado, and Utah. His doctoral research focused on Hohokam household-based craft specialization, and he has continued to build on his doctoral work with examinations of production and exchange at Hohokam sites in the Tucson and Phoenix basins. One of his longstanding research interests is the elucidation of site structure to further our understanding

of social differentiation in the Hohokam pre-Classic and Classic periods.
