Just upstream from the drainage near the Icicle Buttress descent trail, but before Roto Wall? If so, it sounds way harder than when I did it a couple years back.
There's also an easy flow (WI2-3, 30M) up the hill just before/downstream Icicle Buttress, near the base of that wall with the multi-pitch slab routes (Fish Wall?).
Have you gotten a look at The Drip recently?
Good on ya!
