Very good picture! How hard are those routes?
I've been on this wall (Marinelli colouir) in Jan 1980 and my first impression was that here we can find "classic" difficulties (4°-5° UIAA and 45°-65° degrees on ice) , nothing stronger, no unescapable choices, but we must remember that this wall is up to 2400m of difference in elevation ...
nice picture! I wish we had more pictures like this...I see the lines and want to go climbing :D.
give a look to the Nordend routes, much safer and maybe finer :)
