I went up Cairnsmore of Carsphairn (2650 ft) yesterday and there was a
rather nice temperature inverstion with other hill tops standing out above
the mist. An absolutely fabulous day in the hills by the way with wall to
wall blue skies above (and cloud below). Ben Lomond visible to the north and
the Lake District hills to the south.

I went up Bushbury Hill (613ft) yesterday, and noticed the air is quite
dirty. I could just about see the outline of the Wrekin 20 miles away.
Blue sky above at the zenith, dirty grey at the horizon.

It had methinks, at the distance of 20 miles what's difference between the
true and astronomical horizon?
