See Thumper for the general location.From Thumper, "adventure hike" about 100 yards north to a fern covered talus slope. On your left (west) will be the massive slab of the 4th Flatiron. On your right is a west-facing, vertical wall containing 4 routes. This is the route in the center of the beautiful black wall and follows a small corner. Great moves on excellent rock. There is no descent anchor, walk off left (north). This area gets excellent sun even in the winter.
