Spectre of the Brocken Update

I believe that I have inadequately defined the Spectre of the Brocken! I hate it when that happens! I should have said that it is a giant SHADOW, not just a giant. I believe it is one's own shadow, spread across the low hanging fog on the mountaintop. There, that should clear things up! (See this "web" site "link," to which I should have paid more attention than a quick skimming. Gosh, before today I never dreamt there were so many "web" sites about optical phenomena. But I'm glad there are!)
