My late dad had a hunting camp in Elks County, Pennsylvania (on Dents Run if you want to know where my handle comes from). A nearby mountain was heavily strip mined over the last decade or so. Now it's been covered over, trees and grass are growing. It's become the primary site for viewing wild elk in the eastern United States. In Pennsylvania trees grow the way grass does in other states. In thirty years the place will be the forest primeval and environmentalists will be up there hugging trees till the sap squirts out.
LOL!
