Description

This route is more a scramble/adventure hike than a climbing proposition. It is however way cool and should be explored if you are ever in the vicinity of the Royal Arch.

Hike to the spring (hopefully you'll try this when it is dry) and hike West into the gaping cave under some chockstones held in place between the 4th Flatiron and the Lower Tangen tunnel. Climb into the cave and climb up a spiral staircase formed by large boulders, way cool!

This will eventually lead you to the top of the chockstones and into a small amphitheater nestled between the Tangen towers and the 4th Flatiron. This amphitheater is very vegetated and not by good weeds either, so watch out for the poison stuff. I did this in winter after the snow had melted, so the vegetation was dead and flatenned.

Once here, you have a choice to continue up some easy (class 4) slabs that will then place you just North of the 5th Flatiron. If you are into rough hiking you can continue up to the summit of Green mountain by squeezing between the 5th and Schmoe's Nose.

For less-adventurous folks looking to experience the tunnel only, as you emerge out of it, hike South via the saddle between the towers and then East back to the Royal Arch trail.
