Climbing "? (alte BHs)" in the Lavanttal Alps is a significant undertaking, demanding a high level of skill and commitment. Classified as a grade 8/8+, this route represents a considerable challenge even for experienced climbers. The exact details of the route, its holds, and specific cruxes would be vital to understanding the nature of the climb fully. The ambiguity in the name (translated as "Old Bras") also hints at a potential sense of humor or oddity associated with the route, perhaps related to its location, characteristics, or the first ascensionists. Without more concrete information, it's difficult to provide a truly detailed description, but the grade itself suggests a steep, technical climb with demanding sequences and likely a significant amount of power endurance required. Preparation, careful route finding, and solid mental fortitude would be essential for a successful ascent.
