Fantastic, sustained, and very well-bolted. The middle section appears damn blank from below, and turns out to be pretty damn blank when you're on the route. The crux appears to be an undercling/stand-up move into the little dish in the middle of the blank section, but there are plenty of hard moves above and below.
After you come around the corner to the south face of the Fortress, you will shortly come to a large, tapering chimney (Yo Yo Pinnacle--see p. 306, SQL II). This route starts just to the right--in fact, it's safest to start in the chimney for a few moves--and tackles the blank face with an overlap above. To the right of the route is a crack (Camelot) which doesn't reach the ground.
many bolts--very well protected
