Hayley Madl is a producer on The Green Tunnel. She is also a PhD student at George Mason University focusing on Indigenous history in Early America and digital history. Her family has long been into all things outdoors, and she had two brothers complete thru-hikes of the AT as part of the Class of 2021. While her own thru-hike is still in the works, Hayley is settling for diving into the history of the trail and disappearing into the woods whenever she can.
