Well, I've seen Tower 3 Chute at JH quoted at 38 degrees and it is usually full of moguls (unless there is new snow). It's not exactly the same as a "mogul run" but popular steep runs do wind up with some.
Anybody remember what Al's run is? I admit I survived (as opposed to skied) the short top steep section, but even the main part seems steeper than Outer Limits. And it is definitely a mogul run.
