This is a another wonderful easy Flatiron climb. It has a "classic" rating in Roach's Flatiron classics guidebook. There are a couple large runouts (~25-35 feet) on this climb, so I gave it a "s" rating even though other guide books don't.

P1. Start at the southern corner of the rock and head up the east face. A 5.8 varition goes up a thin crack around the corner. Belay below a bulge on the arete or near a small tree (~120 feet, 5.2).

P2. Climb through a bulge, and head up a clean runout slab. Belay near the south edge (~130 feet).

P3. This is the best pitch on the climb. Head up the arete, place some pro in the small crack, and then hand traverse the ridge line to the summit. Enjoy the exposure off the back side into Bear Canyon. The best protection on this pitch is a good smear and a firm grasp.

Descent: sling the summit block with the rope and rap off the back side (west side). We did a double rope rap to the east into the gully north of Fi. This is a better option in my option.


Light rack to 2 inches.


We did a single rope rap with a 60M rope north/east into the gully between Fi and Fo. If you rap to the end of the rope, you will just make it to walking territory - about 40 feet up the gully from the start of Quadratic Equation. Pulling the rope can be difficult, though. Aug 21, 2001

Indeed, Mike, we did the same rap, and it took the body weight of 2 people on the rope to get it to move. So I'm not sure I'd recommend this rap, even though it does set you up nicely for Q.E. Aug 21, 2001
We did this route on 4/5/02 and I agree with both 5.3 rating here (as opposed to Rossiter's 5.0) and the added "s." If you don't like the summit ridge hand traverse it is also possible to traverse straight north across the face from the p2 belay. I got a piece in about 30' out (a red(?) tri-cam at my feet) then about another 15-20' to the large gully running up the face where more pro is available up to the rappel point. Again, your best pro is good clean slab technique (fairly low angle though). The "sqeeze chimney" between Fi and Fo on the walk east from the rap in interesting and fun; don't bring your tubby friends on this climb! :_) Apr 9, 2002
Lying back solo on the hand traverse made it worth going up there. Jun 12, 2004
As an old but beginning climber without much adrenalin, this was an enjoyable route. If I can do it anyone can.

We had 5 climbers going up in parallel (3 and 2). Alan, Byron, John, Chris, and Kevin. After 2 1/2 pitches, we enjoyed a wonderfully clear day (sufficient to see Buckley AFB and DIA).The traverse was my favorite part of the climb as it was my first such climbing experience. The rappel has much loose rock to be kicked onto climbers who are foolish enough to not move out from under the rope after completion. Beware.The hike back is very short and could be done in climbing shoes.

All together we took less than 3 hours from start to return.

This thing is really good. In fact, I did not think 5.3 could be so fun. Fun climbing, good rock, well-defined line, and amazing position.


P1: ~35m to ledge with small tree. Sling flake for belay with optional small cam. This pitch took good gear.

P2: Pull cruxy bulge with really good gear, then run out some easy terrain to an obious ledge below ridge with good crack for belay.

P3: Go up to ridge, place a good piece, and run out the super cool hand traverse for a good while. This pitch deserves the R rating, but you have bomber hands the whole time (and good feet most of the time...). Belay at the rap station.

Rap WEST with single rope off the sling nest (looked good, locking biner is still there with newish slings) and scramble easily south around the formation to your packs.

I think you could do this in 2 pitches with a 70m, but rope drag would be bad and communication very challenging on the last pitch. Jun 20, 2011

Did Fi Fun for fun today in 2 pitches with 60m rope no problem. Small amount of rope drag at the hand traverse but no issue. Rappel anchor going off the west from summit was in fair to good condition. Took a bit of effort to get the rope going on pull-down but manageable. Certainly a nice route for a solo. Aug 16, 2014

It is possible to get off of this rock without a rope, it is delicate and a tad dirty. It feels about like getting off of the Fist/Hippo Head for difficulty. From the summit, downclimb straight east down a gully 15-20 ft until you can traverse north to small horn/flake. From here, delicately walk through a thin slab section until the holds get much better and you can step over to a large boulder separating Fi from Fo. From here, downclimb the north side of the improbable-looking gully to the east or continue up Fo. Sep 28, 2018

I can second Cordis' appraisal of the downclimb, though I find getting off of the Fist WAY more enjoyable than this. This is dirty, and quite thin in places though I probably didn't find all the best ways, either. Oct 13, 2018
