The Boundary Waters Canoe Area has some of the same issues. Campsites inside an 'easy to get to' area are just stripped. Trees cut down, bark stripped off of trees, the fire pit seating hacked at, and food stuffs from washing on the shore.
The forest service ends up digging the toilets out of some really rough pickaxe type terrain, since most of it is a thin layer of soil over the glacier carved granite. God help the poor soul who dumps trash in the outhouse and gets caught.
