A recent meeting between Tribal Nations and researchers from the Prairie Research Institute focused on the cultural significance of freshwater mussels, priorities for conservation and preservation, and opportunities for collaboration.

Longtime researcher Alleen Betzenhauser has been named the new director of the Illinois State Archaeological Survey and Illinois State Archaeologist at the Prairie Research Institute.

Past and present ISAS staff have authored papers in the recently issued Midcontinental Journal of Archaeology (MCJA) on the pre-contact and contact era archaeological record of the Chicago region, guest edited by Dr. Clare Tolmie (ISAS Northern Illinois Field Station Coordinator). 

This volume, the first of two special issues, serves as a reminder that, despite urban growth and development, the archaeological record of Chicago survives in many parts of the metropolitan area, from the end of the Ice Age to the end of the pre-contact period when Indigenous communities were first in direct contact with Europeans.

Recognized for her exceptional contributions, Mera Hertel, a cornerstone of the Illinois State Archaeological Survey (ISAS), has been honored with the prestigious Prairie Research Institute’s 2024 Distinguished Support Staff Award.

Dr. Andrew C. Fortier, a stalwart figure in the Illinois State Archaeological Survey (ISAS) and the broader Midwest archaeological community, departed on November 6, 2023, leaving behind a legacy of profound contributions and fond memories.

It is with profound sadness that we share the news that James “Jimmy” Burns passed away on November 7, 2023. Jimmy was a consummate field archaeologist who worked extensively across the Midwest, Far West, and Southeast over a 40-year career in both cultural resource management and academic settings. Above all, Jimmy was the best friend a person could be and he will be missed forever across ISAS, PRI, and beyond. 

A massive archaeological site in St. Clair County, Illinois, was excavated by ISAS for the Illinois Department of Transportation between 1998 and 2007 to make way for a new bridge over the Mississippi River. ISAS archaeologists excavated some 7,000 discrete “features,” locations of trash-filled storage pits and houses, among other things, near the banks of the Mississippi River.

This spring the Illinois State Archaeological Survey (ISAS) at the University of Illinois Urbana-Champaign will hold its third annual virtual speaker series featuring Native scholars and leaders. The Intersections of Indigenous Knowledge and Archaeology series is intended to center Indigenous voices, increase awareness of the deep Native histories of the Eastern Woodlands, and amplify the experiences and research of Indigenous scholars and leaders. 

The ancient North American city of Cahokia had as its focal point a feature now known as Monks Mound, a giant earthwork surrounded on its north, south, east and west by large rectangular open areas. These flat zones, called plazas by archaeologists since the early 1960s, were thought to serve as communal areas that served the many mounds and structures of the city.

New paleoenvironmental analyses of the north plaza suggest it was almost always underwater, calling into question earlier interpretations of the north plaza’s role in Cahokian society. The study is reported in the journal World Archaeology.

The Intersections of Indigenous Knowledge and Archaeology Speaker Series aims to center Indigenous voices, increase awareness of the deep Native histories of the Eastern Woodlands, and amplify the experiences, research, and knowledge of Indigenous leaders, scholars, and artisans.

The Illinois State Archaeological Survey seeks Archaeological Field Technicians to fill hourly field crew positions for large-scale Phase I, II, and III projects conducted out of our Central Illinois Field Station in Champaign. These are temporary (with potential of long term), full-time (40 hour/week), non-benefits-eligible, field/laboratory positions that may also involve some additional fieldwork, data processing, and specialized-analysis opportunities. Technicians will need to relocate to the Champaign area.  In-house training in ISAS methods is provided, and lodging and per diem are paid on out-of-town projects.

This spring the Illinois State Archaeological Survey (ISAS) at the University of Illinois Urbana-Champaign continues the Intersections of Indigenous Knowledge and Archaeology Speaker Series, which aims to center Indigenous voices, increase awareness of the deep Native histories of the Eastern Woodlands, and amplify the experiences,research, and knowledge of Indigenous leaders, scholars, and artisans.

In November, Illinois State Archaeologist Tim Pauketat delivered a lecture sponsored by The Archaeological Conservancy. In his talk, he described insights gained about Cahokia and future plans for outreach and research activities conducted in collaboration with Tribes. 

This spring the Illinois State Archaeological Survey (ISAS) at the University of Illinois Urbana-Champaign will hold a virtual speaker series featuring Native scholars and leaders. The Intersections of Indigenous Knowledge and Archaeology series is intended to center Indigenous voices, increase awareness of the deep Native histories of the Eastern Woodlands, and amplify the experiences and research of Indigenous scholars and leaders.

The Illinois State Archaeological Survey offers a GIS-based tool that draws on more than a century of data to predict the probability of encountering an archaeological site in any 2-acre section of Illinois. Land owners, developers, preservationists, and other Illinoisans can use this tool to proactively assess and protect archaeological resources while enabling sustainable development. 

Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city’s rapid expansion.

ISAS archaeologists investigate "borrow pits," where the people of Cahokia extracted much of the soil used to build their famous mounds. The scientists are beginning to think these ponds held more meaning for the original city builders than archaeologists once assumed. They also hope to study another overlooked feature of the city of Cahokia: a causeway that cuts through the site.

Dr. Tamira Brennan, who previously worked at the American Bottom Field Station as a coordinator, researcher, and ceramic analyst, is returning to the Illinois State Archaeological Survey as the section head of curation. ISAS houses one of the most extensive archaeological research collections in the state of Illinois, which is used by researchers from around the world to gain insights into our history. 

The Prairie Research Institute recently honored the two Illinois State Archaeological Survey (ISAS) staffers for their contributions to a long-running collaboration with the Forest Preserves of Cook County (FPCC). 

As we all seek to limit spread of COVID-19, this event will be postponed to 2021.  

The Illinois State Archaeological Survey will host a visiting scholar conference May 30–31, 2020. Toward the Middle Range will focus on the intersection of theory, method, and case study through the lens of the New Materialisms. Up to 15 participants—local, national, and international—will be selected for this two-day conference, which will feature both public and private sessions. Papers will be compiled into an edited volume.
