Congress would direct the Interior Department to study the Cahokia, Emerald, and Pulcher Mounds in Illinois.
The study would weigh whether these sites should become part of the National Park System.
It would also look at other ways to protect and explain the sites, such as partnerships with state, local, nonprofit, or private groups.
The Interior Department would consult with governments, organizations, and interested people, and estimate the costs of different options.
A report to Congress would be due within 3 years after funding is first provided for the study.
