It's here. Staring at the mountains, down the lake and valleys, that a moment of realisation comes that we could be the only people standing there for millions of acres. 

There are not many places - with the exception of the ocean or desert where you can think, as far as I can see, as far as I can contemplate, we are the only person here. 

That significance, of the insignificance we play in this landscape, is not lost.
