This route climbs the gully on the far right side of the east face of the First Flatiron. In excellent condition, this route would be trivial, however more normal conditions will require some rock climbing, some sketchy climbing on snice, some thin ice and some proper mixed climbing. Figure out how to get off the ground and into the bottom of the gully. Cruise up this with little in the way of protection until you reach a nice big patch of shady snow where the gully widens. A rock belay can be found here. The next pitch may well be the crux. Climb up a right-facing corner with some thin ice and to a belay at a tree. Pull past this tree into another snowpatch. From here, we climbed into the corner on the right side of the gully and rock climbed easily to the top. From the top of the gully, one may continue to the top of the 1st Flatiron or just drop over the other side of the ridge and walk back down.

All in all, this is a satisfying Flatiron experience.


Rock gear from nuts to hand size.

Really an awesome route. The conditions window for it is extremely short, so if you think it might be "in", get up there.

I recall wishing for a #3.5 or 4 (old style) Camalot for the wide layback to the tree belay. Other than that, just your standard Flatirons ice rack. Heh! Jan 14, 2007
Hey. I thought you guys might like this video on the Silk Road :… Jan 15, 2007

Ha Ha. That video is nice but the wrong Silk Road.
I climbed SR 2 years ago. It was thin but fun. Much thinner than the tr on here. The start along the side of the big boulder is tricky with crampons and ice tools but after that it's nice up to the tiny cicle crux. If you shorten the 3rd pitch then both the 2nd and 3rd have great belays tucked back under a ridge. Good pro slinging the tree. Used a few cams and a nut or two for the whole route. After the crux, we went left to the large ledge and then up the face and topped the ridge by the little tree just a couple of gendarmes away from the summit. Jan 31, 2009
As George stated, this route has been known for over 50 years as the East Face Gully NOT Silk Road. It is wrong and incorrect to assign another name for this route just because it has also been climbed as an ice/mixed route. Feb 19, 2010

Jack, I just used the name from your old guidebook. I think that it is kind of nice to have a separate name for these routes as ice routes because scratching up them on a cold winter's day is a remarkably different experience than cruising up it in a pair of rock shoes on a warm summer evening. You also frequently end up climbing slightly different features. That said, I would be happy to change the name. Feb 20, 2010

Climbed this gully on Feb. 10, 2011. Full 60m runout to first belay, no pro, but easy climbing on good ice, snow. Second pitch, with no ice, required awkward layback behind flakes to trees. Our next pitch took us past the ledges (delaminated ice) where we chose to traverse to a tree (right of route) and start descent.

Overall, a great outing, I'd like to try this again when there is more ice and continue to the top! Feb 17, 2011

Anyone know if this is in right now and what the ice quality is? Mar 3, 2012

During an amble up the east face of the First this morning, I noticed a ton of crampon marks on the north ridge. It seems to me that there should be a dialogue about whether it is appropriate to be climbing the north ridge in crampons. The north ridge is enjoyed by lots of people. The rock is relatively soft, so it is easily affected by crampons and there is a pretty natural way to get off Silk Road without heading to the summit. I think that it would probably be best to preserve the condition of the rock on the north ridge. For some perspective, perhaps we should look to the UK where it is considered a faux pas to climb classic rock routes as mixed routes unless they are completely white with rime. I think a similar perspective makes sense on something here that is as well travelled as the north ridge of the First Flatiron so the thousands of people that climb it every summer can enjoy it.

I share Ben Collett's concern here, regarding crampon scratches in the rock of the North Arete (or anywhere that is a popular, or even non-popular, rock route). When Kirk Miller and I did Silk Road in late Jan. 2007, we exited right, a pitch above the end of the gully, and found an established rap anchor, allowing us to do one 60-foot (?) rap to the ground from the ridge. I admit that our frontpoints hit rock at times during our climb. Feb 2, 2013

I've always wondered if this is a problem. Do you think there is damage to the rest of the route as well? Mar 27, 2013
Here is a trip report from a recent ascent of Silk Road:… Feb 15, 2014
A #3 and #4 Camalot are very useful on several pitches, as are a single set of cams all the way down to #00 Metolius. Mar 5, 2015

East Gully is East Gully. Winter, Spring, Summer, or Fall. Snowy, icy, rainy or leaf strewn.
Silk Road climbs most of East Gully then exits up left wall. Following a dagger that hangs off from the slab above. There is a little, tiny tree there to sling near top of overlap. If there is some ice and snow there, follow that to the summit. Bravely linking runnels of snow and ice out on the main face, delaying escaping to the summit ridge as long as possible. Take your crampons off as soon as you are comfortable, trying to save the rock (as well as your crampons).
This route takes one all the way to the summit. A long, very lovely alpine route in downtown Boulder.
