1. Follow a crack past a bush, then past a right-facing corner to a left-facing corner at a small roof. Over the small roof (crux), then move up and left to a belay tree. 5.8-, 60 feet.
2. Do the second pitch of Morning After. 5.7, 90 feet.
3. Scramble up and left to a large, obvious right-facing corner. At its top, go past a roof (crux). The top is not far past that. 5.9-, 100 feet.
I don't think this gets done too often but the climbing is very worthwhile. We didn't do the second pitch; it was described as contrived, and the second pitch of Morning After is quite nice. The crux roof would be more difficult for someone who is short.
Location
10-15 feet right of the large, left-facing corner with the short chimney that marks the start of Rusty Trifle. It is a short walk from the Frog's Head area.
We did the same thing for a 2nd pitch. I think you did well to describe it that way. The 2nd pitches there overlap a lot, and it makes more sense just to keep going up than to wander around.
I do remember feeling that the 3rd pitch was reachy.
