Excellent pic of this fantastic couloir. Canalone Neri, also known as Canalone della Tosa, is regarded as a route to Cima Tosa, rather than to Crozzon. Maybe you should have posted your image to the Tosa page, or, even better, to the route page for the Neri. It's a great picture anyway: with a dusting of snow, Tosa and Crozzon look fabulous. (If you look at my profile pic, you'll find that I'm partial to this view.)
Thanks a lot for your award.
