Description 

Start up Cannonball Corner and diverge as the topo shows. Easy aid to the end of pitch two. There were some loose things that we may have skipped cleaning on the pitch two traverse because we were gunning for the top in one day. This would all go free and be really nice, maybe 5.11, maybe harder with pump factored in to the rating. It might be very tough to retreat from the end of pitch two.

The third pitch is outstanding. Hands and fingers up to a great ledge. Might be just 5.9. Like the good stuff on Cannonball, only thinner and thus "better". I wrote "dry bivvy" on the topo, even though we got up in one day. The important thing is that from the end of pitch one to the end of the crux aid the route stayed dry during a huge rainstorm.

Pitch four is an upside down rurp traverse. Bad swing into the dihedral wall if it all rips, thus A4-. I don't think anything ripped for the second, so maybe not too bad. A rope left hanging from the top would perhaps be lasso-reachable for an insanely exposed, upward, jumar escape.

Our last pitch is also the last pitch of Cannonball. Easier, unless it is wet and dark.


Location 

This route is located close to the cave-like zone cut by the Rusty Dagger. The Black Wall's alcove shape, wetness, joint patterns, and rock glacier signal, at least to me, the potential for catastrophic mass wasting. I'd like to make the point that most routes on this wall, not just Undertow, are unusually dangerous.

Alcoves usually form within cliffs located under plateaus, like we see in Canyonlands. The flat surface above the cliff collects groundwater, the water weakens the rock, and the wet zone weathers into an alcove. Most alpine cliffs have only small summits above and dry quickly. Climbers know the Black Wall has a summit plateau that soaks up water like a sponge, taking days or weeks to dry out. Compare the dripping rim of the Black Wall to the once familiar and now abandoned Yosemite cliff, Glacier Point. The largest rock avalanche off Glacier Point is proven to have been the result of a mistakenly located outhouse adding lubricant to the wall's joints. It's not raining poo up on Mount Evans, but a wetter wall is hard to find.

What really worries me most are the vertical cracks forming Cary Granite, Good Evans, and Cannonball Corner. These cracks increase in size, from left to right, towards the undercut center of the Black Wall. Road Warrior is widest and the little "J" at the bottom helps visualize the whole pillar as a collapse on temporary freeze-frame. Maybe it's time to move the belay bolts to the offwidth's left side, so they don't end up in the rock glacier below.

Glaciers certainly delved the cirque, but this wall is so actively falling apart that any signs of glacier ice scouring it have long ago become a part of the rock glacier below. Rock glaciers are more common under loose mountains. They abound under the rotten volcanic peaks of the San Juans. The rock glacier below the Black Wall is not even under a peak. The talus on it is large and fresh.

UNDERTOW is even closer to the alcove and the center line of the rock glacier. The route follows a large, undercut, flake. But the climbing is some of the best on the wall. The same forces that have, and will, cause mass wasting of the Black Wall also created one heck of a steep alpine route. Irresistible?


Protection 

My memory is that rurps and small copperheads are key to aiding the summit roof. Everything below could be done with small wires and cams up to big hands.

A bolted rappel route might be nice from the end of pitch two. It didn't look too steep, but we didn't test that. If two 70m ropes don't reach the base ledge, then a bolt anchor would be needed and probably have to be placed in the line of fire of the horrible summit drips.

Thanks for adding this stuff Ken, I was wondering about the aid routes on the Black, it seems they need a repeat. Can you post beta on the other aid routes?

Mighty generous placing my name first on this route...Trout led all but the top out and I'm sure I never would have visited the Black Wall in the first place were it not for his vision.

Is the RURP traverse visible in the main picture for cannon ball corner up in the upper right corner the thin crack traversing that roof from right to left?

I believe that Asa Firestone and Matt Othmer did the second ascent of this route last summer. They were bummed to see that an old RURP was fixed in the crux as they were up there to claim the first ascent. Absolutely beautiful looking line though I hear that the top seeps quite a bit.

After two seasons of cleaning, replacing bolts, and fighting wetness in the later part of the alpine season, I was finally able to free this gorgeous line with Brad Wilson last Saturday (6/23/12), with both leader and follower freeing every pitch. The whole route is probably no harder than 5.11+, but as it is very sustained and at high elevation, it sometimes feels harder.

The majority of the route follows the aid line, except for half a pitch that completely avoids the A4- roof traverse. The rock has cleaned up well with maybe only a few suspect rocks that may come off with a crowbar. The climbing is tenuous, sustained, fairly sharp, and gear is sometimes tricky to place (a green/yellow Alien offset cam is really nice at the top of pitch 1!). However, the entire route takes great gear with clean falls, no runouts, and sinker finger locks are to be had throughout. As Ken points out, even though the upper pitch is often wet, the rest of the route stays dry. 

The pitches break down like this:
Pitch 1: 5.11- (130 ft). Start the route as Ken says on a ledge below the large dihedral of Cannonball Corner. Climb up easy ledges up and right to a small hand crack that leads you to the start of the main Undertow dihedral system. Clip a good piton and climb the sustained dihedral thru some cool flakes (green/yellow offset Alien very helpful here) and up to a stance on a small ledge. The anchor takes finger-sized gear.

Pitch 2: 5.11+ (40 ft). This pitch could be combined with Pitch 3. Continue up the dihedral (crux), pull around a small bulge to a ledge with a bolt. A finger-sized piece or two can back up the bolt. 

Pitch 3: 5.11- (50 ft). Continue up the dihedral, past a thin flake that I couldn't pull off despite several attempts, and up into the 35 ft roof traverse (pumpy!). Belay at the lip on a small ledge. Anchor takes hand-size and small cams. 

Pitch 4: 5.9 (110 ft). Climb straight up the fun hands and fingers corner to a good ledge. Anchor takes finger-sized cams. 

Pitch 5: 5.11 (50 ft). The Undertoad Variation. Continue up the corner to the roof. This is where the original A4- traverses left under the roof. Instead, stay in the crack, which cuts thru the right-side of the 10 ft roof. The lip of the roof is very sharp, so the trick is to back-clean as much as possible before the roof, and from a good stance under the roof, place one or two medium-sized cams in the middle of the roof on VERY long slings (we used 3 shoulder-length slings clipped together, which worked great). Undercling the roof to the right (avoiding the A4-), pull the lip, clip a fixed yellow Alien (wires broke so I couldn't get it out, but it's a good piece), and finally face climb a couple moves to the left under a massive shelf to an amazingly exposed, hanging, bolted belay on the aręte. 

Originally, I set a natural belay at the fixed yellow Alien, although this required the next pitch to traverse around the very sharp aręte. Not only was this very dangerous, but it didn't allow the pitch to reach the summit. The face moves getting to the aręte and keeping the rope off the sharp lip of the roof is the reason it's key to have the long slings under the roof. It was considered to place one or two bolts on the face to keep the rope off the sharp lip instead of the long slings under the roof; however, using the long slings was completely safe as you can get good gear in at the lip. 

Pitch 6: 5.10 (70 ft). Sometimes wet. Traverse left from the aręte under the shelf for a few moves and join back with the original aid line. When the shelf becomes a manageable bulge, clip a high bolt and face climb up to the aid line belay ledge. Continue up past two more bolts to a big ledge, which is where the collected water drips from when it is wet. Climb up and right past a piton and finsh in the chimney or on the aręte to the left. Traverse left on big ledges to gain the summit and belay bolts. 

Rack: doubles to #1 BD Camalot, with extra finger-sized cams, one #2 BD Camalot (extra #2 and #3 could be useful).

A big thanks to Will Butler for conceiving of freeing this route and his hard work the last two seasons trying to make it safe and climbable.

Good work, guys! Was just up there a couple of weeks ago and rapped in to check out that line. After seeing your chalk and gear, I realized it was an active project, so didn't pursue it - but I am super curious: what was the old flimsy wooden board doing strapped like Ahab to that last bulge?

Radical! Can't wait to try it.

Nice work, Shaun! The line looks kick-ass, I hope I get a shot at it before the end of the season.

Thanks, guys! I still need to clean the "Ahab" board from the last pitch. I think the biggest reason no one has done this line before is that the final chimney on the last pitch seeps water over the "Ahab" bulge straight down the last pitch. For the last two years, the seeping started in July and didn't stop for the rest of the season. I put the board up there in a crude attempt to divert the flow. Ha! I think it may have done some good, but the last pitch isn't too hard and is essentially a sport climb. The rest of the route stays dry, so maybe it just adds some spice at the end of the route. If you're not into climbing wet granite, just drop a rope down 90 ft from the top to the anchor on the aręte like Ken suggests. It may also be possible to add a variation to the left with a couple bolts that would join back on the left of the "Ahab" ledge where Canonball joins into Undertow.

Ah, that makes sense - the Ahab board. I thought maybe that's what you'd beat me with if I'd have decided to try it before your send....

Do I have to have the offset aliens?

7/30 Update: Probably wet for the season!

Hi Jay, sorry for the delayed response, but I think you would be able to get away withouth the offset Aliens. It's only the first pitch that they are handy for, and there are other gear opportunities, so it wouldn't ever be too run out. I don't typically place stoppers unless I can't get anything else in, but I would imagine you could use stoppers, especially offset stoppers. On one attempt, Brad didn't have the offset Alien on the upper half of the first pitch, but he did find some RP placements I didn't notice before. Let me know if you get on it. As far as I know, it is still awaiting a second ascent.
