S. 1516

Cahokia Mounds Mississippian Culture Study Act

Energy and Natural Resources Committee · Sen. Richard Durbin (D-IL)

The bill would direct the Department of the Interior to study three ancient mound sites in Illinois—Cahokia Mounds, Emerald Mounds, and Pulcher Mounds—to evaluate whether they deserve designation as a National Historical Site. The study would assess the sites' national significance, determine if they're suitable for the National Park System, explore alternative preservation options, and estimate costs, with findings reported back to Congress.[AI-Generated]
