35-second read · 4 questions answered below
The bill directs the Secretary of the Interior to study Cahokia Mounds, Emerald Mounds, and Pulcher Mounds in Illinois to determine if they are nationally significant and could become a National Park System unit. It also requires examining alternative preservation options and their costs, with a report due to Congress within three years of funding.
The study primarily affects residents and local governments in St. Clair and Monroe Counties, Illinois, along with tribal nations tied to the Mississippian culture and preservation or tourism organizations.
The study could lead to future federal action, such as national park designation, but does not itself change how the sites are currently managed.
