Volunteers will not enter Cementland directly, and the cleanup will occur around the perimeter of the property. This cleanup is led by The St. Louis Cleanup Crew and The Chain of Rocks Community Association. Everyone deserves a clean, litter-free neighborhood. Come out and help us clean up this area, so that the people who live, work, and play here can enjoy trash-free lives!

The festival will be hosted by Open Space STL, The Audubon Center at Riverlands, and The Army Corps of Engineers, and will feature free food, drinks, and activities for the whole family!

We'll also have a trash contest for all clean up participants. Did you find the biggest trash? The weirdest trash? The most bottles of Fireball? Bring them to the picnic for bragging rights... and prizes!
