This grade 6 route (UIAA scale, likely translating to around 5.10a in Yosemite Decimal System) on the 25-30 meter Wasserrillen (Water Grooves) formation provides sustained and engaging climbing. The water-worn features that give the area its name offer interesting holds and sequences. Expect technical footwork and thoughtful route finding as you navigate the face. The sustained nature of the climb means endurance is key, particularly towards the top. A solid head game is also important as the exposure increases. Overall, "Brontosaurus" is a rewarding climb that showcases the unique character of Wasserrillen.
