Old Pueblo Archaeology Center’s Third Thursday Food for Thought will feature a free online Zoom presentation – “Revisiting Santa Cruz de Terrenate Presidio” by Dr. Deni J. Seymour on Thursday, October 15, 2020, at 7:00-8:30 p.m. (Arizona/Mountain Standard Time). In 1775-1776, the government of New Spain created a series of frontier presidios along its northern frontier. Three of these are in Arizona. Archaeologist Deni Seymour, Ph.D. conducted a multiyear field research program at what remains of Santa Cruz de Terrenate, located along the San Pedro River near Sierra Vista. This is the best preserved of all the Spanish period presidios in the American Southwest. Join Dr. Seymour for a discussion of the history of this adobe fortress, information about recent archaeological and ethnohistoric investigations, and revisions to interpretations of work carried out by archaeologist Charles Di Peso almost 70 years ago. New findings include 240-year-old footprints, information relevant to the location of the Sobaípuri sites of Quíburi and Santa Cruz, and insights into hygiene, population, and status.
