Green Mountain Pinnacle isn't. It is, however, at little jab of stone appended to the North flank of the Fourth Flatiron. It sits in the forest on the West (uphill) end of the Fourth Flatiron, but is sufficiently distinct that you can scramble all the way around it.

Getting There

Using Rossiter's North guide, Green Mountain Pinnacle would be the 8th named rock with The First Flatiron as #1. My guess is that people use many approaches to reach GMP. Our approach was always to hike the Mesa Trail to a spot South of the Third Flatiron. A trail heads up Bluebell Canyon, and after a short ways one can take off South of the trail and bush-whack to the apparent West end of the Fourth FI. This always felt as though we had hiked to near the top of the hill. When you finally see it well, through the trees, you won't miss it. The North wall is very yellow. If you look for it, you can see GMP from Baseline road in Boulder and pretty much keep a good eye on it hiking the trail.

IMO the easiest way to find this rock is to start at Chatauqua and head up the Royal Arch trail until you reach the pass. At the pass leave RA trail and bush wack due west up the hill for quite a ways. There is a talus field a few hundred feet up which can be followed until it peeters out. Then just keep going up, to and fro, until you see the yellow wall and a small kairn on a ledge near the wall. You'll know you're there when you see a broken diagonal crack, leading to the roof above (Death & Transfiguration 5.11b). Jun 17, 2005

I have found two trails to GMP. From the pass follow a faint trail west just north of some small Flatirons. As you pass the last one you have two options:

1.) Angle to left and up the hill to the top of the ridge line. Once you are behind the "Hammerhead" Flatiron head straight west until you bump into the Last Flatironette. Pass this on the right and hug this formation until you reach GMP.

2.) Angle almost straight North (right) until you hit a talus field. Follow a path west through this field with an occasional cairn until you hit the tree line. Near a large fallen tree, you will find a good trail that switch backs up the hill until you are North of the formation.

I think the second option is more straightforward with less bush whacking. Jun 1, 2010
