Chuenisberg Ravage

The sector Ravage is steep and has a long history. It was once home to the hardest route in the world. Ravage is a route that has now been on sighted by Adam Ondra. The Bohemian born, Basel resident, Wenzel Vodicka worked with  the leading French climber Antoine Le Menestrel to make the first ascent back in 1985. Originally graded 8b+, it is now thought to be 8c, and still sees very few ascents. Vodicka later turned his attention to the wall to the right, but continually failed on one move, despite many attempts over many years. Frederick Nicole eventually redpointed the route in 1996, and impressed with the standard that Vodicka had reached, named it "Enfant de Boheme". A few years later another Frenchman, Pierre Bollinger added an even harder route to this wall, "Fusion" graded 8c+. You can see a video here.
