FATMAP difficulty grade
A fairly easy (5.0 YDS) scramble up the second flatiron.
This starts from the "Flatirons Loop trail and follows the left side of the north slab of the second flatiron.
Stay on this, past a jump, until you're above the 1st/2nd Flatiron trail, then follow the rock up to the left where there's an obvious, tree-assisted down-climb to the trail.
