The Fifth Flatiron is basically 500 ft of 5.5 fun, which we did in two rope stretching pitches. Not as much of an outing as the 1st or 3rd, I made it to work on time that afternoon. There is even a sweet little surprise in an alcove on the summit. If this route was closer to a trailhead it would be a MEGA classic, but it remains for those of us who don't mind a hike.
