"The origin of Waligóra is unclear, but the prefix "wal" (similar to what it says in english might have something to see with its steepness."
Waligóra (Polish) is a fairy tale character, a kind of giant.
thanks ! I'll correct that. I used "might" so forgive me ;)
p.s: do you know that there is a Baligura hill in the basque country ?
A Baligura? Funny.:) Well, in Romania, a "gura" means the mouth of a river.
