This route is a easy lead, TR or solo.
Climb up a clean slab with excellent horizontal edges, then onto a ledge. This might be 5.3. Continue slightly North into a space between the two pillars- the Ginseng and the Second Pinnacle and get to the narrowest gap between them. Stem up this gap to get to the summit of the Ginseng Pillar, which is airy, but goes on big holds (5.4?).
To descend, you can down-climb back into the notch and then down-climb North/Northwest through a different slot to the ground (5.1?)
From the outside west side of the second pinnacle of the Gregory Amphitheatre, near the sport routes, continue down South/Southeast below the Ginseng Pillar through a notch. Look up 6 meters to see a split block laying against the wall- the five-foot crack that splits this goes from thin to fist.
Just right of this block there is a chimney/slot, and a little right of that, a well featured face with good horizontals, perhaps 5 meters down-hill from the split block and 3 meters down from the slot.
Climb the face on good holds up into the slot above a ledge and continue to climb up between the Second Pinnacle and the Ginseng Pillar to the top of one or the other.
A standard light rack will afford you normal 'flatirons' protection- which is to say that there will be some spaces between pieces. But the route felt reasonable and secure even as a solo in tennis shoes.
