I *sure* wish I had seen this post before I attempted to solo the Waterfall Route this spring! For your information, the current state of affairs is exactly as Klaus has described above, and the Waterfall Route is unclimbable.
I was completely lost up there, and had no idea why I couldn't find the route. Answer: the route is now lying at the base of the wall. Sheesh.
I am also wondering if more rockfall has occurred in this area since the first fall? By my observation, the fifth belay of Waterfall Route has been obliterated. It used to be on the ledge straight left of the fifth belay on Klaus' route Get Whacked.
