I went back to Barclodiad y Gawres again - because I wanted the specific view you get from there - it had been overcast all day, and by late afternoon I noticed that the sun away to the southwest was producing a bit of backlighting out to sea, and I wondered what it would look like.
Well the incredible visibility below the cloud layer, combined with the backlighting from the sun, was producing the most amazingly sharp sea / sky horizon that you could cut yourself on it was so sharp.
And the lower end of the Lleyn Peninsula was almost silhouetted against the backlit sky -
There must have been a bit of diffraction going on, because you can see the low lying land right down at the far end of the Lleyn Peninsula - you don`t often see that from Anglesey.
From Barclodiad y Gawres it looks as if Bardsey Island is attached to the main land, however it isn`t, you just can`t see through Bardsey Sound.
It is a shame that Barclodiad y Gawres isn`t a bit higher, as the adjacent hill to the south was hiding what would have been a great view across to some of the hills further up the Lleyn Peninsula.
Right round in the other direction up to the north there wasn`t the backlighting from the sun, but there was still the same superb visibility, and the same razor sharp sea / sky horizon.
There may not have been any backlighting, but instead the sea had a sort of fluorescence that meant that it was lighter than the clouds above the horizon, so the islands round Rhoscolyn Beacon were standing out amazingly.
