Prehistoric & Historic Water Use in Arizona Lecture Series

Join Pueblo Grande Museum is hosting our Arizona SciTech Festival Lecture series beginning January 31 through February 28, as part of the 3rd Annual Arizona Scitech Festival.  Join us for one or all of our lectures discussing current research and discoveries of prehistoric and historic water use in Arizona.  These lectures are free and open to the public.  Visit our Calendar of Events page at pueblogrande.com for more SciTech events at Pueblo Grande Museum and to learn more about the Arizona Scitech Festival visit azscitechfest.org.

Friday, January 31, 11:30 a.m. to 12:30 p.m.
Topic: An Interdisciplinary Approach to Understanding Canal Dynamics
Guest Speaker: Bruce G. Phillips, M.S., EcoPlan Associates, Inc.

Archaeological testing and data recovery at the Hohokam farmstead site of Punta del Ambar, revealed information that indicates residents had a reliable source of water, and used a nearby riparian area. A multi-disciplinary analytical approach is being applied to reconstruct the evolution of the wetland.

Friday, February 7, noon to 1 p.m.
Topic: A New Type of Water Control Structure in Hohokam Canals
Guest Speakers: Kathy Henderson, Ph.D. & Connie Darby, Desert Archaeology, Inc.  

Archaeological excavations downstream from the Park of Four Waters at Pueblo Grande revealed a surprising find of large distribution canals branching from main trunk canals with a well-preserved adobe and cobble weir. This water control feature, presently unique among Hohokam irrigation structures, is the focus of this presentation.  

Friday, February 14, noon to 1 p.m.
Topic: Why We Study Prehistoric Canals: A Geoarchaeological Perspective
Guest Speaker: Gary Huckleberry, Ph.D., University of Arizona

Dr. Huckleberry reviews current geoarchaeological projects involving prehistoric canals in Arizona and how the study of these ancient waterworks allows us to test ideas regarding population dynamics and regional abandonment. Research considers how humans deal with environmental change — a modern topic as we deal with population increase and climate change in the Southwest.

Wednesday, February 19, noon to 1 p.m.
Topic: An Ancient Legacy to the Modern World – Prehistoric Irrigation in the Salt River Valley
Guest Speaker: Jerry Howard, Ph.D., Curator of Anthropology at Arizona Museum of Natural History

The Hohokam created the largest irrigation systems in the prehistoric New World. One often overlooked aspect of prehistoric Hohokam irrigation is the impact that it had on later historic agriculture. This lecture outlines what we know about prehistoric irrigation in the Salt River Valley and addresses the impacts it had on farmers in the historic period.

Friday, February 28, noon to 1 p.m.
Topic: The Origins of Irrigation in the Sonoran Desert
Guest Speaker: Jonathan Mabry, Ph.D., Historic Preservation Officer, City of Tucson, Arizona

Recent discoveries of buried canals in the Tucson area have extended the history of irrigation in the Sonoran Desert back to 3,500 years ago, requiring new models of the transition to agriculture and development of village social organization in this region. This lecture summarizes these findings and their implications for Southwestern prehistory.
