According to the route description that we had read before, this would be an F+ climb, with the crux being a short couloir of II+/III.
Before we knew it, we were already at that couloir. Apart from a big one at the bottom, the rocks in the couloir were fine, and there were plenty of hand- and footholds. I believe that rating it as III is an exaggeration. Still, that same couloir, plus the slab (I/II) immediately before, also makes me think that the climb itself shouldn't be rated F+ but PD.
Great consolation prize Date Climbed: Sep 11, 2012
4th & last summit summit of anglo-dutch international alliance (self plus rgg). Original plans for Mont Blanc had to be shelved due to fast approaching bad weather - but there was just enough time to slip this one in. And it proved to be a worthy day out climbed from the beautifully situated Lac Blanc refuge. Summit ridge quite airy but fairly straight forward - although I was happy to put the rope on for the 'chimney', which was the crux of the climb, less than 150m below the top. We easily beat the bad weather - but enjoyed views of it setting in around the higher summits across the valley.
