What it does
This bill directs the Secretary of the Interior to study three ancient Native American mound sites in Illinois (Cahokia Mounds, Emerald Mounds, and Pulcher Mounds) to determine whether they should become a unit of the National Park System. The study will evaluate their national significance, explore preservation alternatives, consult with Indian tribes and local stakeholders, and estimate costs—with a report due within 3 years.
