pointing out & naming all the noteworthy things to see across the horizon & also gave a braille translation
I'm not blind, but as I understand the world, those things exist whether or not they can be seen. They are still there (I think) if one goes up t the viewpoint at night or in the fog. Unless you seriously doubt the persistence of physical objects through time when you cannot see them, it is hard to see the problem with a blind person standing at the viewpoint and saying to himself "in that direction is Cadair Idris".
A few years back there were a set of radio programmes that David Blunket made of his sound recordings of the landscape at night, because at night you can hear further. The recordings and his monologues were some of the the most remarkable radio I've ever heard. So I'd agree that you can be blind and be very interested in the horizon.
