Classic route with long approach and descent. Time to climb the route depends of your endurance and skills. It is shorter than Steck -Salathe but harder and takes about the same time. You can link this route with Lost Arrow Spire and end up with glorious Tyrolean traverse, but in this case you need to spend one more day to fix ropes from the Rim to the notch, or ask your friends to do that.
My friends Chad Suchoski and Zander Brennen did this route few years ago and wrote nice reports on ST:

http://www.supertopo.com/tr/Lost-Arrow-Chimney-Trip-Report-9-19-09/t416n.html.
I recently climbed this route with Zander and think that this remarkable route should be added to MP.
We did route in the end of September with temperature mid 80F and it was in the shade almost all day. Still two liters of water each of us had was not enough.
We used second rope for hauling a small bag with food, water and excess gear.
Reid topo has not many details, but the general line of the chimney unmistakably brings you to the notch.
P1. Start route in the right crack than after 70 ft cross to left crack and ascend 70 more feet to belay ledge. 140ft, 5.8
P2. straight forward 140 ft, 5.9. . We linked p1&2 with 70ft of simulclimbing
P3. Main feature of the pitch big wide roof 5.9 [left side in]. This roof can be bypassed on left at 5.9 thin cracks and face moves. 80 ft. Belay on Horseman ledge or link with next pitch
P4. Safety Valve - first long OW stretch, but not the crux of the route. 120' 5.9
P5. Wide chimney pitch with cracks in left and right side of the chimney. You can use both #6s on this pitch. 100 ft, 5.9
P6. Was mental crux for me because I read Chad's TR and his description of this pitch:
"next pitch which was a fun finger tieback on the side of the chimney with a little stem across and onto the face where you're supposed to pass a couple bolts and back into the chimney. There were no bolts, but there was a piton. After making the most awkward move in climbing history to gain access back into the chimney, (picture your right foot in a small corner, your right hand on a knob and leaning over a chimney trying to reach the other side of the wall more than 4ft away. Then just letting go of the knob and falling into the wall bridging the large gap with your body. Now turn and lunge for that suspect chockstone [which rolls a bit] and pulling yourself back into the main part of the chimney "
I really did not want to do this weird jumping on face and especially back. But there is a way- you just go straight(completely ignoring Reid's topo bypass) in the crack and climb flare/ow at 5.10 with good pro #6 . 100ft
P7. Chimney, wide chimney all the way. Rotten to the top of the pitch and in term of pro- the worst pitch 120 ft, 5.8
P8. Climb increasingly hard chimney to new bolt. Crux - long reach for handhold just after you clip the bolt. 100 ft, 10a
Chad and Zander replaced two old rusty bolts for shining one in 2009, thanks
P9. Start with 5.10a flare/OW (right side in) . Then from the middle of the pitch you have two options
a) follow the crack system to second upper 10a flare climbing mostly outside
b) enter deep into chimney and bypass upper flare inside. You and your partner need to be small for this variation
P10. Have two options (we did not find Harding hole) . See also enclosed Zander's topo of last pitch
a) climb 5.9 crack in the corner (looks like better option), b) but we climbed 5.9 thin hands ( felt harder than 5.9)
Now you are on the notch - find first set of bolts on your right in the base of the Spire and go home. Or continue up...
Approach: same way as for Lost Arrow direct starting trail behind SAR base . Or climb SunnySide Bench route as approach and from there hike up the slab to the base of Chimney route.
Descend two options:
1. If you end up the notch - do 8 double rope rappel from Rohrer rappel route ( rappel chart enclosed)
2. If you pre-fix ropes and climb in addition Lost Arrow spire - walk off Yosemite waterfall trail which ended up at Camp4
Double from green Aliens to #2 Camalot. One #3.
Big Gear: We used 2x#6. It probably be about same if take one#5 and one#6. We took #4BigBro and did not use it

Take knee pads. Mine are a mess. The route takes more time than half dome RR. Don't let the moderate grade fool you. After pitch 7, you are half way done. A few notes. We didn't use the recommended belays on every pitch. We didn't run full pitches together either. The first few pitches are easy. Turning the roof on pitch 3 looks like a horror, but it is very easy on the left by way of a finger crack. The top of the safety valve gives you an idea of what is to come. Expect many feet of this type climbing. The OW on pitch 5 is easy. Pitch 6 is odd and wonderful stemming. My partner said that going straight up the OW squeeze was 5.11. Going around right was easier. Pitch 7 (the rotten chimney) is easy, but dangerous and intimidating toward the end. A yellow totem cam might have made it R instead of X. Pitch 8, with the good bolt, is dangerous. Imagine an open flaring green chimney with a bad fall (before reaching the bolt). This stretch was at my limit. After this, more flaring squeeze. Pitch 9 Starts with 70 feet of flaring squeeze. The bolts on the topo are useless, but cams fit in the back. About 70 feet up, tunnel in a tight squeeze, and then back out above chock stones. This pitch is hard. Pitch 10 is pure joy, steep hand and finger cracks.
We took a set of offset nuts from about #4, double cams to #1, and a single "2,3,4,5,6. Seemed about right, and allowed us to make two or three piece belay anchors. Two quarts of water were plenty, but expect to burn 1000s of calories.
The Rap map isn't accurate. However, it is easy to find the anchors. Don't use the anchors out left on the second rap. The good anchors are hidden lower in the chimney (straight down) The only rap station that wasn't straight down was second from the end. Easy to see, 150 ft, and a bit climbers left. A few hanging belays are very uncomfortable. Jun 29, 2015

Link 1/2 (100ft Simul)
Mostly trivial climbing, there is an improbable looking roof on pitch 1 seen from the ground, climb up to this and move left at the base of it.
Link 3/4
Bypass Offwidth roof by climbing crack on left -- easy. Safety valve starts easy, ends harder, protects with #6
Link 5/6
5 is mostly trivial until Super wide stem, stay in middle crack using the right crack for help (left off). I found start of pitch 6 to be easy, you can wide stem the entire lieback, protects with .75/#1, this leads to easier O/W.
Link 7/8 (50ft of simul)
If you link these two there will be some rope drag at the end.7 I found not rotten, theres just not really any pro in the beginning, but its very easy. Some harder climbing at the end of 7, start of 8, but it can be protected. I thought the offwidth flare at the end of 8 was the easiest on the route, but could have just been my style. Lieback at the end with back against wall.
Pitch 9
Crux offwidth for us, long thrutchy flare off the belay protects with both 6's, to an easier squeeze above. Tunnel behind the chockstone, its bigger than the Harding Slot, but I still had to take off my helmet, and extend my knot.
Pitch 10
This ones funny. easy climbing up to the 5.9+ thin hands, short enough, place a #1 high and go for it. We went right here on less than desirable rock to a traverse on shitty rusty pitons and a rusty fixed nut. This is not confidence inspiring, but you can place a #4 directly after traverse. from here its a wide stem with a discontinuous thin hand/finger crack on the right. This is way harder than 5.9, or at least felt harder at the end of this route.
Rack I would take doing it again:
1 .2
2 .3-#3
1 #4, #5
2 #6
no nuts
This route could really be cleaned, we found more tat on this route than ive ever seen. Unfortunately we were not prepared to haul a bag of tat off the route. Bring a knife and a trash bag! Aug 6, 2019

I think this route is really interesting from a historical perspective, and had a few cool sections (like beginning of pitch 6). Oct 22, 2019

In terms of beauty, adventure it’s incredible. Better than the Steck, DNB, or Rostrum. It’s super out there. You think about how long ago the FA was, it’s mind blowing.
Now in difficulty it’s a harder line. A step up from the Steck. In some ways it's kind of a 5.10 wide for 5.12 trad climbers kind of route. (You don’t have to be capable of valley 5.12, but it’s really hard.) The profile of other commenters illustrates this - see 5.13 climber (stevecurtis) talking about some pitches being at his limit. I'm a 5.10/5.11 climber, but survived. Though, our strongest leader was a 5.13 trad climber. We did have a Merlin #8 along - that cut the danger factor down significantly. A 5.10 aid-baller could probably get up this with a cheat stick, and a #8 or two.
We did not end up linking pitches. We got started a bit late - 9AM started climbing. Topped out at 10PM. We were a group of 3 - the 3rd came up on mini trax. We had 2 packs, pulled them up most of the time, but did have 2nd/3rd bring them up occasionally. Nearly every pitch is sustained. The climbing is enjoyable if you're in the mindset for it. If you're just not having a good time, then bail.
P1 - grassy on the start, but gets better. Sustained 5.9. Least enjoyable pitch.
P2 - up and over a 5.9 roof, then easy (easiest pitch on the route). Starts getting fun.
P3 - two options - recommend going left. Our leader went up the wide in the middle - dirty and burns energy.
P4 - Safety Valve pitch. This was easier 20 years ago. I led it then. Could barely follow this time. Dunno. Felt harder than Ahab.
P5 - Wider pitch - felt closer to 10a. I got going without the full rack. That slowed me down - pulled up the #5.
P6 - A 10a pitch. Fun. But beware the small chock stone after the crux moves.
P7 - 5.9 fun chimney. The #8 and the #6 made this reasonable.
P8 - OK, this is where sh*t gets real. John led this. John is a 5.13 climber these days, generally not afraid of anything. He stepped on the bolt. Yep. Kind of hard. The upper part felt 5.10+. Not a squeeze, more a stem. So, enjoyable. But on lead, scary. (Someone more aid climber-like could maybe get past this with Totems + a cheat stick.)
P9 - It was 8PM at night by time I got going on this, had a pack on. After 10 feet I opted to pull up the second pack and jug the line. I really want to go back for this pitch. The pitch ends at a really cool cave. Nice bivy/nap spot. This is probably not where the Harding Hole starts - I think that starts higher up.
P10 - OK, this pitch gets weird. Up, then across right, up, back left, clip a sketchy pin, then into an alcove I think where the harding hole goes, then up a 5.10b/c finger crack.
Rack - we had a standard rack of double cams (aliens, totems, bd's mixed) to #2, 1x #3, 1x#4, 1x #5, 1x#6, 1x#8 Merlin. We got lucky, found a 2nd #4 on route. Were happy. We used the #8 quite a number of times.
Note: the first time I tried this we only had up to a #4, and no knee pads - didn't go so well, we bailed at p6 that time.
Notch Rappel:
From the notch, work your way out to the belay bolts for the spire. They're on a little ledge. This is the first rap anchor. Rap straight down, not to climber's left. The second rap anchor is just over a lip. There are a couple bolts. If for the second anchor, you find yourself on a sandy big ledge that you could bivy on, you are off route! The sandy ledge is off to the left, it has a bolt and a pin. That is a belay anchor for Lost Arrow Direct. Do not go that way - we almost did, would have been a very long night. The rest of the raps go down a wide chimney system, then down the face.
Also - WTF is up with all the tat rope in the chimney?? I've never seen anything like it. I think there were three abandoned ropes, all caught up in chock stones. Bring a knife, cut it loose, let nature flush it down the chimney. Or better, haul it out. I didn't have a knife. Nov 12, 2019

P4 is the first real taste of the route, and if it's anything other than a small challenge it's probably wise to bail. Pitches 8&9 are worlds harder. The 5.9 generally felt 10- and the 10a felt 10+.
I didn't see a piton for the traverse on p6. I went up to a higher one that seemed off route.
The crux on p8 is extremely unpleasant. You have to crank on chossy, sharp, chiseled pockets while smearing on kitty litter.
The anchor on top of p8 doesn't have a bolt like the topo shows but needs one. The only gear is in a hollow flake and the climbing off the belay is some of the hardest on the route.
For following the rappel route look for 1 new wedge bolt at every anchor. The 2st 2 rappels are only 80'. Then a few ~140' that might go with an 80m. The final 2 are ~90'. Oct 27, 2025
