The Fourth is probably the longest of the major Flatirons, extending nearly to the summit of Green Mountain. The formation, however, is actually broken into three smaller subflatirons, separated by gullies which are hidden from the normal view from town. The northernmost extension of the 2nd sub-Flatiron is actually Green Mountain Pinnacle. The route really isn't much fun, requires bushwhacking in the gullies between the subflatirons, and culminates in the most anti-climatic summit of the 5 major Flatirons. I give it one star only because it takes you to the top of the 4th Flatiron.
Approach via the Royal Arch trail. Take the trail 100 yards past Sentinel pass. The 1st sub-Flatiron at this point nearly touches the trail and can be identified by a cave 150 feet up.
Climb up to the cave (actually an arch) and exit on the left up to a ridge. Climb the ridge until it is possible to drop into the gully between the 1st and 2nd sub-Flatirons. Bushwhack up this gully to an obvious crack splitting the face of the 2nd sub-Flatiron. Climb the crack/gully (and face on either side) to the "hanging garden" near the top of the formation. Hike through the woods in the "garden" to the gully separating the 2nd and 3rd sub-Flatirons. Bushwhack down this gully to a crack splitting the face of the 3rd sub-Flatiron. Climb this straight up to the summit area.
For a very detailed route description, see Roach's guide to easy Flatiron routes (possibly out-of-print?). The Falcon guide description is very similar to the one above.
Descend to the north of the Fourth Flatiron eventually connecting with the Green Mtn Pinnacle approach. The gully on the south of the 4th (which I descended) is not recommended.
As with most east face Flatiron routes, it didn't look like you could get much pro...or good belay anchors for that matter. Probably best to solo this because the leader pretty much is anyway.

I'd agree about the recommendation bit, anticlimactic summit, and grunge factor. I'd have to disagree about the soloing bit. There certainly were anchors for belays and light protection opportunities for the leader. Did this some years back for curiosity and it is probably tied for the least interesting of the East faces of the 1st-5th Flatiron with the 2nd. Not a destination climb but a completion climb.

Actually, it's possible to do this climb without any gully bushwhacking. Climb the first piece all the way to the top (of this piece), then cross the upper end of the first gully and climb near the north edge of the east face of the second piece to the hanging garden (joining the route described above). Do not bushwhack down the next gully, but just cross it and get on the east face of the last piece, traverse left a bit and head up. Alternatively instead of doing this last piece you can move north behind Green Mtn Pinnacle and climb Challenger instead (a bit better climb, IMHO). Although anti-climactic, the true summit of the Fourth is the highest of the 4 Flatirons.
Agreed, do not descend south of the Fourth Flatiron.

i remember having a grand time on this, there was a great wide crack/ groove part that got my heart going. But a couple days later i broke out in huge boils of poison ivy.......

We climbed the top section of this today after putting up the 5th and made the mistake of bushwacking over. I found the climb to be unappealing and offers sparse pro. The groove described above is 5-7" wide 4-6" deep (like a rain gutter on your house)and offers few placements. Walking up through this looked to be a drag. We climbed the face to the left, finding a few flakes and cracks, and ended up pulling up over a few bulges using nubbins with horrendous runout. Higher up, not much better. In my opinion, this climb is a one timer, never to be repeated, at least by this poster. I recommend not bushwacking from the 5th because of the density of poison ivy and density of obstructons. If you decide to make up your own mind on climbing the 4th after the 5th, make sure your legs are covered. I fear the poison ivy is incubating on my skin at this very moment!

Sorry you had an unpleasant time on this rock. It isn't as nice as other Flatirons, but I still enjoy it. Yes, protection is sparse. I usually solo it, but I know this isn't an option for many climbers. It doesn't seem much more dangerous to solo than to lead this baby because of the runouts.
Also sorry that you didn't know the first credo of Flatiron scrambling: NEVER venture between the 4th and 5th Flatirons. I've done this once - which is all anyone does it. It is as you described.
I've done the 4th at least five times. It is a big climb with some grubby sections, but I love the crack you describe above. This is a cool, unique feature in my mind and fun to climb actually.
I've linked the 4th with the 5th before and the best way seems to be to climb the 5th first and descend the south side (climber's trail there). Then do the 4th and descend on the north side past Death and Transfiguration (make sure to pause, look up, and say, "Damn, what a cool crack!"), and down to Sentinel Pass.
As an interesting note, Bill Briggs has climbed all five Flatirons via their East Face routes, Chautauqua Park to Chautauqua Park, in 2h5m! That's smoking! I keep track of junk like this and, as far as I know, the 4th is the only numbered Flatiron that hasn't been climbed in under an hour from Chautauqua Park to Chautauqua Park (though it seems very clear that Bill Briggs could do it).

Sheryl Costello and I climbed this route a couple of years with some friends from out of town, and planned it as an introduction to Flatiron climbing. As such I don't recommend it; it's a bit of a slog, and although the climbing is easy, the pro is sometimes poor and often non-existent.
That said...the route does have some virtues. For starters, you won't have to contend with the crowds like you would on other Flatirons. And a visit to the secret "hanging garden" is pretty cool. And hey, when you finish the tenth pitch (it seemed to us like much more!), you'll be considerably more beer-worthy than your pals who did something "easy". Right?

An interesting variation on the first section is to climb inside the cave/arch, traversing all the way to the back where it is possible to squeeze up through a short chimney (looks impossible at first). This will land you higher up on the east face and an easy scramble straight up will get you back on route.

I don't really understand all the negative feelings about this climb. Some of the Flatirons are beautiful cruises, and some are wilder adventures. This falls into the latter category, but it also has a variety of cool climbing. Also, definitely do the "extra credit" summit about halfway up. And then do Takin' Care of Business.
