There are two nice head walls, with the crux being at the second. Really thin face climbing, it forces you to string together your moves. Mostly feet until the crux and then be prepared for some arm exercise... very crimpy.
Location
Second from the left end of Solar Slab, to the right of the fabulous Solar Flare with its big, arching layback... to the left of Tava.
Protection
7 bolts to a 2-bolt anchor. Very well protected in all the right places.
Actually, yes, I have climbed it... don't agree with the 12a. In fact, I'd say 11a. There's a tough pull just before the end, but no wild moves (unless that ear shaped foothold has broken off since last I climbed it 2 months ago). Besides, I can't climb 12a :)
