The University of Iowa Office of the State Archaeologist (OSA) is an organized UI research unit established in 1959. Now entering its seventh decade, the OSA continues to actively develop, disseminate, and preserve knowledge of Iowa’s human past through archaeological research, scientific discovery, public stewardship, service, and education. While the roots of Iowa Archaeology are much deeper than OSA’s existence, the two have long been intertwined. This presentation will trace Iowa Archaeology’s deep historical underpinnings and OSA connections including results of recent OSA activities.
