Update:
A few years after this, (11/2015 I believe), Jason and I were invited by our chief and other chiefs (chieves?) in the area as well as other people from our tribe. The graffiti had been cleaned off by state workers and we followed up with a cleansing of the land.
A few years after that, Profile Rock crumbled. :(
