Binary Surd

A decent route following the R side of Fo. Wander up the Mallory Cave trail past Red Devil, the Box, angle SW, and head to the third strata of Dinosaur Mt. This lies just L of the relatively-narrow channel/groove capped with a large chockstone between Fo & Fum. Probably not heavily traveled but worth the effort for those in search of a brief (240') flatiron explore. Start approximately 30 feet from the R edge of Fum in a shallow, inviting, L-angling groove with good face holds.

P1. Angle slightly L up this shallow groove. Find a crux about 90' up as you hop up past an angled ledge. Now head up. Continue to a tree at 120' for a belay (optional).

P2. Continue up to a second crux with double sidepulls and good smearing as you shuffle up. This is somewhat reminiscent of the South Platte here. Move slightly R and then continue to the top on easier terrain. Hopefully you'll find a pleasant breeze at the summit.

Descend via a 50' downclimb with a few 4th or low 5th class moves to the slot between Fo & Fum (the next flatiron N). Move N up over a boulder and head for a hole/cave to the Fum-Dum col. Wander down a loose trail back to the base.

to #2 camalot with an emphasis on smaller pro/cams.
