I've climbed 'Rechts vom Biwakplatz gerade hoch, bei Platte Crux, 50m Seil', a challenging route graded 8/8+. The route's name translates roughly to 'Straight up to the right of the bivouac site, at the slab crux, 50m rope'. It appears the route features a crux section on a slab. The name emphasizes a direct line and a specific location relative to a bivouac site. The 50m rope length suggests a single pitch climb or a section within a longer multi-pitch route. The route itself is not specified, but it seems to be a very hard and demanding climb.
