Holly Marsh recently returned from Washington D.C. where she was honored for the 2009 National George B. Hartzog Youth Volunteer Award. The National Park Service chooses just five of their 175,000 volunteers to honor with this award. Holly was chosen because of her extreme dedication- she volunteered for over 270 hours for the National Park Service last year. Not only is she an incredible public servant, but she is also an outstanding student. Her interest with the National Park Service began with an Avalon trip to the park headquarters in the Minnesota Science Museum. We like to think that project based learning contributed to her achievement.
