We were asking ourselves the same question. It doesn’t really warrant one compared to the 2 right most climbs on that face, as they only have 1 bolt on each at about half height. But Wounded Knee is heaps harder, more insecure and stays that way right to the very top(even with 2 bolts).
But i think the last bolt on wounded knee would just keep you off the ground…..maybe:)if you pitched off at the top.I don’t think the R rating was for the bolt. If they were that bad(which they weren’t)an X might have summed up the potential catastrophic failure. But they were in reasonable condition, even with their homemade nature.
