Anthony Honick, resource manager, and Christian Clendenning, park ranger at Crooked Creek Lake, show how to plant and cover an Eastern White Pine sapling during a volunteer tree-planting Earth Day 2021 event they hosted in Ford City, Pennsylvania, April 22, 2021. Approximately 20 volunteers attended the event to plant 200 tree saplings, which included Eastern White Pine and Swamp White Oak, donated by West Penn Power. Crooked Creek is one of 16 flood control reservoirs within the Pittsburgh District of the U.S. Army Corps of Engineers. Several reservoirs and parks throughout the Pittsburgh district celebrated Earth Day by hosting either a volunteer cleanup or tree-planting day.
