Years ago this was my first experience with arch vandalism when on a visit to Princess Arch I found this under the deck and a small firepit below. Best I can figure whomever camped under the arch had climbed up and created this graffiti with charred wood. The next time I returned, several months later, the drawing was gone. Remember, camping under an arch or within 300 ft of a trail is illegal in the Red River Gorge.
