This is a really wide and seldom visited Flatiron with only a few established routes. The longest route is on the left side at almost 600feet. There is also a shorter route that looks really fun up the shorter center of the formation, and another separate line on a section to the North. It seems like there is a lot of real estate to choose your own adventure.
Take the Mesa Trail to the junction of the Shadow Canyon connector trail. Head southwest until you see the giant cairn on the right. Follow the old quarry road back North. Turn left, at a cairn, and up the Maiden approach trail. Turn right before the Madein Boulder. Stay East of the Fatiron. This is the next big rock to the North.
