I climbed this route yesterday. I had been a bit concerned about what seemed to be unprotectable exposure exhibited in this photo. But, the good news is that he is off what seems to be the standard route.
The standard route, which is well described in Roach's book, will have you climb the 'slender blockette' to the right of this gully. Climbing on the slender blockette is good. It's a bit runout as is standard for Flatiron climbing.
