German name: Probably Köpernik Glaser (See here)
Pronunciation: AFAIK The stress isn't on the "i" but this "i" is a long vowel
Geology: Not granite but gneiss
Access: No info on access from the west (Ramzova, Branna)
History: Not sure about Wroclaw Bishopric, but I don't think Poland has ever reached the summit of Keprnik. "The mountain of three kingdoms" seems impossible anyway.
Corrections (at least few) done. I need to rewrite the access, by the way last year I rode it a second time from Ramzova ;)
As for the "mountain of three kingdoms", you know Yasek, I'm not a born-Easter-Central-European (despite the map shows I am almost), but my eyes still see well, and I just rewrote what was on the signs of the educational trail on Keprník...
Perhaps lands/counties, not kingdoms/countries: Silesia, Moravia and Grafschaft Glatz (Ziemia Klodzka)?
I'll tell you when I come back ;)
Maybe they mean Bohemia, Moravia and Silesia, but then I guess Snieznik would claim the title. And what about Smrek and the Pass of Three Borders? Well, write it all down when you get there next time.:)
