Obviously impressive, but ...
There's a statue on a fountain in Zermatt to a local Guide, Ulrich Inderbinen (1900-1990). It records that he climbed the Matterhorn (obviously with clients) 370 times. The Guides' fee for climbing the Matterhorn is about 1,800 Swiss Francs. It's very popular ...
If one looks closely at the start one sees a large bronze statue on the face (Virgin Mary), and a plethora of fixed ropes. I am afraid that the Hornli ridge has gone from being impossible, to a hard route, to a trade route, to a bread&butter for the guides.
But it is still impressive, despite some people claiming it is entirely loose rock. Well, there is a lot of loose rock there in some places, but that tooth still sticks up awful high, with some awful steep faces.
Sue said she'd let me do it with a Guide, but it seemed a bit commercial these days.
The HornliHutte and HornliHutte Hotel are just below dead centre. The photo of the start of the ridge was taken from above that, a bit to the right.
