Also, I don't think anyone takes their lawn mower up there. I would imagine that the grazing by the caribou accounts for the grass being taller in some spots than in others.
Other than those comments, all I can do is suggest that you borrow my glasses. I honestly do not see what you are referring to.
I do not know the source of the pictures. What I do know is that the first person that I saw post them, well over a year ago, is someone whom I trust and who has actually been there and can personally attest to what the terrain is like. They are not that person's pictures, however. I suggest that you follow some of the links on this thread and the links on some of the threads linked to this one and see if you can find the source yourself.
