Though not as continuous as the other Flatirons routes, this has one superb pitch on it. Your goal is the gully that lies between the Pullman Car and the South Block on the Second Flatiron. Start at the Gutter bouldering area and climb easy mixed ground towards said gully. The gully itself currently has a vein of ice in the back of it that is a couple of feet wide and 1-3 inches thick for approximately 50m. At the top of this ribbon of ice you'll find a nice ledge to belay from. Easy mixed climbing will take you to the into a bit of a bowl under the ridge. If you climb up the right side of the bowl, you'll find yourself a brief scramble away from the trail.
Location
Start at the Gutter on the south side of the Second Flatiron.
Protection
Some rock gear perhaps. A couple of stubbies could be placed.
