The Umph Slot 

The 150ft length is a Very Rough estimate. If you try to do it in one pitch and come up short......you have been warned.

Don't even have an illusion that this route is anywhere near 5.8+, unless your 4'2" and have no shoulders. You can also start this by going up The Owl and continuing left where you would go right to the bottom of Supersqueeze-5.6.

Mark must be a Hobbit or a Dwarf to get inside this route. Climbed on the outside this route is well into the 5.11 range. I recommend two #5 Camalots and a #3 Big Bro if aiding this baby (the only way I could get up it). Nothing else really fits because you can't reach in far enough to place a #4 Camalot. You do place some smaller gear at the start, but be careful you don't place it too deep and you'll need to go find Mark to retrieve it.

The way I have done it (twice) was one side in and one side out. Then you can pinch the rock bewteen your thighs for friction (we called the right side of the crack "Mrs Bubb" as a joke) while thrutching up the with arm-bars and poor jams. Be warned, if you slip in this position, you may damage "the goods. I'm a fairly small guy (5'10" 165lbs) but have VERY long arms, and I'm pretty flexible. So, I fit further in than most people and could reach further back than most who can fit in. I found the climb to tick in at about 5.10c/d.

Very body-size dependent. Smaller people have an advantage, but so do apes with VERY long arms and big paws.

I saw Dave Miller "wine master to the stars" free solo this without chalk or shoes-no lie!!!

Hard to give this nasty 10' stretch of climbing a difficulty or a quality rating. For one thing, it's completely size dependent. As someone who is pretty narrow front to back, I could just barely fit inside -- removing my gear sling made the difference between success and failure. As a squeeze chimney, the way I climbed it, it was considerably harder than the notorious squeeze chimney section of the Harding Slot; this would make Umph Slot at least 5.10. As an offwidth, the way someone wider would have to climb it, it's probably that much harder.

Note that most of the way there is good hand size gear (and handjams) in the back, if you can reach.

Do this back to back w/ Supersqueeze for the full on abuse program -- 20' feet of climbing that will feel like that many pitches.

This has got to be one of the nicest offwidths in Boulder (although granted, there aren't that many). I found it to be very sustained throughout the overhanging section, with very insecure arm barring and toe heel moves, until a killer chicken wing about 10 feet out can be obtained. I used a #5 Camalot and moved it along, until leaving it behind near where you can get up on the less steep upper face. I'd call this test piece 5.10d and felt it had moves as hard as the crux on Crack of Fear. Great route!

This climb is unratable. Stuff yourself in it and call it whatever you want. I'm about 190 and getting inside the crack isn't even an option. My chest won't fit in, but I can get some good chicken wings and work the lip gaston style with my right hand. I use a #3, #2, #5, #4.5 Camalots, with some extra #1s or #2s for the anchor. Placing a #3 low on the pitch keeps the rope out of your way if you fall out.

I'm not a big dude--5'9", 145 lbs., and I had to climb out of the crack, chicken-winging hard with my left arm, kind of gastonneing/smearing with my right hand. Hard to believe that 15-20' of climbing gets you so thoroughly pumped! My pushing muscles--triceps/pecs (and my adductors, with regards to Mrs. Bubb!)--are aching today with nary a pain in my pulling muscles. Re: gear, we used 2 #2 Camalots low in the crack, one about 1' above the other, and a #6 Friend, pretty tipped out, 1' above that. If you aid this thing, take several #5 Camalots or #6 Friends, but for free climbing, I would say just place a #2 Camalot as high as you can and then punch it. David Goldstein is right: this thing is definitely harder than the squeeze section of the Harding Slot.

After having butterflies in my stomach all day, I went for it. Climb this baby left side in, as if it wasn't already obvious enough. For the first 8', you can climb and place gear in the hand crack inside. I placed a red and gold Camalot to start. Once you start moving up you are forced outside by the laws of physics. Don't let that scare you, bust into a "chicken wing" it's the only way. You can also heel toe with your right foot. Place a number 6 and inch your way to the top.

Stuggle violently
up the overhanging slot.
Umph - 5.8 my @$$.

Nothin' like doing the chicken wing thing and then putting a major stress on your funny bone. I was not laughing though at this "5.8" that my partner drug me up. For me, it was probably 5.9 A1 (seconding, I grabbed the rope).
