I don't know specifics but the story in the Asheville paper makes no mention of a map. The Middle Prong is 7900 acres abutted on the south by the Blue Ridge Parkway and the east by NC 215. A cell phone is great but has limited value if one is lost. Luckily a good outcome was reached. Use of a map and compass are critical in the woods, and the woods in the south can be THICK!
