Did you know that the OSA is part of the University of Iowa campus? Our facility maintains the Iowa state archaeological repository with over 4 million objects from Paleoindian, Archaic, Woodland, Late Prehistoric, and Historic cultures. Consider stopping by on your next trip! We welcome both individuals and school groups to take a personalized tour of our facility. See archaeology research and lab work in action; tour the repositories; learn about archaeological field and lab equipment; and explore our comparative and teaching collections including prehistoric and historic artifact types, lithic (stone) resources, fresh water bivalves, botanical specimens, and faunal collections of amphibians, reptiles, birds, and mammals.   

Most tours take approximately 30 minutes. To inquire about an OSA tour, please contact the OSA Education Director.  

We especially invite researchers to make an appointment in order to view and study collections and archival material. Classes are also invited to make a guided tour appointment.

All tours can be scheduled for any time of year.
