Pourquoi? Is there some rule that says hills and monuments MUST be invested with dignified names?
No, nor should names with a legitimate claim to history be consigned to the dustbin of fashion. The Golden Fleece pub here is now known as the Rat and Parrot. The Plough pub by the station became The Harlequins for a couple of years before reverting to the Original Plough! I've no problem with new or humours names for anything but they better be as good as what went before and they better not extinguish valuable etymological information in their quest for a passing claim to fame ;-)
