> Anyone know about the state of Unknown Wall VS since rockfall in Jan 2013?
As others have pointed out, stabilisation work is now underway (I think), but the whole area is still banned.
I'm not entirely sure this answers your question about the state of the route though. As far as I'm aware, all rockfall was way further to the left, on some of the less popular routes beyond Desecrator. The route "Unknown Wall" was not affected at all, but the area was restricted because further rockfall (in the same place) could roll large blocks down the slope.
I suspect there may be a bit more vegetation on the first pitch due to reduced traffic last summer, but other than that I wouldn't expect any major effects.
