Assuming those purple dots on the map are locations of designated rare cliff communities (and the white boxes are not trapping  cabins) I could see a few campsites being closed but not all on every lake within the shape that's crudely drawn.

For that matter, they shouldn't have marked them. Some of us curious types have big feet.

I found an area on a lake once that had flagging tape. So of course I got out to see why. On the tape it said Quetico foundation so I paddled away not wanting to disturb anything. I asked but never heard back what it was they were marking.
