Climbing "Haifischflosse" (Shark Fin) in "Nasenkamin" (Nose Chimney) is a memorable experience, particularly given its grade of 6+. The Nasenkamin is a classic chimney route, known for its tight squeezes and sometimes awkward positions. "Haifischflosse" specifically refers to a prominent fin of rock you'll encounter during the climb, likely requiring a bit of stemming or bridging to navigate past. The 6+ grade suggests a sustained level of difficulty requiring solid technique and good strength endurance. Expect to be challenged by friction-dependent moves, potential route-finding issues within the chimney, and the need to protect adequately. Prepare for some grunting and scraping! This route is a test of character as much as climbing skill, demanding commitment and a willingness to embrace the unique (and sometimes uncomfortable) nature of chimney climbing.
