When a couple of us went up the Grand Cascade last November, the in situ rope was in reasonable condition but the krabs on the deviations were completely rusted shut. I'm sure someone will be able to give you some more up to date info though!
I know that 2 weeks ago a couple of guys came out of Peterson, I think that means it mustve been rigged as they didnt take any gear for it, kind of a last minute decision. Don't know about the condition though, hope this means something useful.
Grand cascade is rigged. The rope on climb up cigalere inlet ( at junction with smashing inlet) is in a bad state. We cut and re rigged it as best we could so it is usable but not ideal and a bit short. Tuck shop pitch in bye George also rigged and is fine. Info correct as of weekend before last.
