Hey Mike. Yes, Nunan is the sit-start problem to the left of Greasy. I remember it having some sharp little crystals. V3 - I think I got the FA. On the opposite side of the boulder, Dave put up another V3 called Looming. It has a jump start to good edge and then goes up and right, escaping to the right side slab.
I think you may be looking at the wrong line. I can see the scars (and a chalked up sit-start hold) in one of the photos of GGGG. That is not Nunan. If I remember correctly, Nunan climbs a crystal line to the left.
