OHC and Hopewell Culture are joining together to cross-promote several events, all revolving around World Heritage Day, April 18 and are related to the Newark Open House on Sunday and Monday April 14 and 15.

But here is how Hopewell is participating:

The Mound City Group Visitor Center is open every day of the week from 9am to 4pm. Visitors can speak with rangers and watch the 20-minute interpretive film. We will also be highlighting the National Park Service World Heritage Junior Ranger program and badge for families. This is also available every day and free.
