Join us at the Visitor Center to celebrate the 50th Anniversary of Earth Day and show what Black Hill means to you! We will be creating our very own Litter Letters, an international community art project and we need your help. First, we will work together to clean up litter in the park, then separate the recyclables from the trash to complete our giant Litter Letters art installation. Stay to unveil our art project to the community and enjoy a campfire with s’mores. For All Ages.
