Black September 

A superb line.

Fantastic climb with the crux arguably being the thin crack at the start

I didn't find the start that hard, but I like fingers. I thought the moves through the wide part near the top were significantly harder...and probably harder than 5.9.

I didn't find any 5.10 on this climb, just easy 5.9. Maybe I didn't look hard enough.

Excellent crack climb with bomber hand jams. Protects very well, super fun.

I also didn't think the finger crack at the start was too hard, and agree that the wider section at the very top seemed to be the crux. From the ledge (at the crux), the crack still takes hand jams above shoulder level, but below shoulder level it's a chimney, so no real feet, or at least awkward feet.

The rest of the climb seems like lots of 5.8 moves, a few 5.9 moves, but with nice rests every 8-10 feet, including two no-hands ledges. So I wouldn't call it sustained - definitely a notch easier than Nova Express on Snowshed.

Eats #1 and #2 camalots, didn't use a #3

Agreed on the top wide section being the crux. Its certainly a small step up in difficulty from OHC.

The route consists mostly of 5.7 - 5.9 splitter hand jams, hence all the "classic" ratings. But be aware of the awkward crux at the top!

Perhaps I'm rusty from the offseason, or am completely oblivious to an off width technique that makes this section go at 5.9. But I was both a little confused and spooked up there with my body awkwardly wedged in a wide crack with nothing but a couple non-bomber hand jams to advance on. The jams are deep (about 2 feet) inside the wide crack. As you reach for them it feels like your shoulders are going to get stuck inside the wide crack, especially as you start to go up, because the wide crack constricts upwards. You are standing when you start this sequence, but there's not much of anything for feet to advance on. I feel the next 3-4 moves are easily 5.10

Once you do get out of the wide section it is more bomber hand jams to the rap anchors. A 70m rope will allow you and your partner to rap all the way to the bottom of the ramp. If you only have a 60m, expect to down climb the 5.0 ramp. Bring smaller pieces #.4 BD - #3 BD with emphasis on the #1's and #2's. I placed several bomb proof nuts on this route and would highly recommend taking them along as well. If your belayer is not climbing this route, or doesn't think they can retrieve all your gear, you can clean some of it or all of it on the way down from the rap station with little effort.

Ya.... I was doing it wrong... Finally got back on this for a red point. My OS attempt had neither the respect, nor the technique to send this incredible line. Just absolutely classic. It's 5.9. Just don't make it your first 5.9 on gear! Definitely no O.W. on it. Haha... get on this splitter!

I don't know, Tyson, I think you're doing it wrong. Not trying to slam ya, just putting it out there so others aren't scared off.

Tyson, I have to agree with Aerili, it sounds like you're approaching the wide section incorrectly. There's no reason to get inside the chimney.

I just climbed this again and have to say it's one of my favorite climbs at Donner. Not too hard, but no give away, and just fantastic jamming from fingers to wide hands (I'm not sure I would say OW - but maybe I have big hands)

I think I would also redefine the crux like this: technical crux is the finger crack right off the deck, and the strength crux is the wide section at the top.

You guys are 2 late, I am officially 2 scared. 2 moves of wideness is 2 many.

FYI: The fixed piece - red rigid stem Friend about 1/3 up the route - is gone. It is back where it belongs (original owner).

Superb crack line. Excellent pro throughout. Agree on the technical crux is the beginning section of thin finger moves getting off the ground - maybe 2 intricate moves at 5.9 then goes easy on mostly 5.8 fun with secure hand jams onward and up, with the occasional single 5.9 moves mixed back in to keep your attention. The wide off-width/half chimney section leaving the last ledge is no harder than 5.9 if you approach it the right way (sorry not trying to slam or downgrade the gumption/ climbing ability of other posts).

No real chimney techniques or off-width struggling is required to get off the deck. Warning beta spoiler: A decent, though not secured, hand jam is within reach if you move up by smearing on the corner of an overlap inside the chimney and take advantage of the sweet edges and pockets on the face right of the crack. Place a bomber piece high up, commit to the jam and features on the face, and you will be rewarded with glorious hand jams to finish off this awesome fun climb.
