Nearing the top of the crux pitch

Seasonal Raptor Closures ***** RAIN AND WET ROCK ***** The sandstone in Zion is fragile and is very easily damaged when it is wet. Holds rip off and climbs have been and will continue to be permanently damaged due to climbers not respecting this phenomenon. After a heavy storm the rock will remain wet, sometimes for several days. PLEASE DO NOT CLIMB IN ZION during or after rain. A good rule of thumb is that if the ground near your climb is at all damp (and not powdery dry sand), then do not climb. There are many alternatives (limestone, granite, basalt, and plastic) nearby. Seasonal Raptor Closures MORE INFO >>>


The Moonlight Buttress, as it is most commonly referred to, is one of the most popular aid climbs in Zion, and, as a free climb, is perhaps the most spectacular, and arguably longest and hardest, sandstone climb in the world. This stunning route tackles the namesake feature, a proud prow of rock that juts out from the wall behind it, via a singular, peerless crack that extends for 1000 feet from base to summit and never widens to more than an inch or two... the Moonlight Buttress is a feature of unparalleled, parallel perfection.

Ed. Note: It should be noted that the route already exists in the Mountain Project database here, described at a 5.8 C1 climb, but due to a lot of requests for free climbing beta, I'm submitting this description of the route as well.

First freed in 1992 by Peter Croft & Johnny Woodward, the route was originally rated 5.13b. That rating has since settled to 5.12d, but even this reflects the overall effort of the climb and not the single hardest moves on the route. This has been evidenced by a number of onsights over the past few years, and most recently, Alex Honnold's free solo of the route in an astonishing 1 hour and 23 minutes.

The Moonlight Buttress is a sustained journey up nearly flawless rock for it's entire length. It has pitch after pitch of difficult Indian Creek style splitters and corners, a few enjoyable face climbing sections, fantastic exposure, and great belay ledges. What follows is a detailed description of my experience on the route that may provide more beta than you're after. If this is the case, refer to the free SuperTopo description that is floating around on the web, or one of many guidebook descriptions.

Approach: Drive into Zion to a bend in the road and park in the lot on the left (Big Bend parking lot), or, continue on for 500’ to a paved pullout on the right. The Moonlight Buttress is obvious. Continue on foot up the road, drop down to the river, and cross near a huge boulder on the far side. Pick up a great climber’s trail to the base of the route. Begin the route well to the left by scrambling up a 4th class passage to the first belay. The approach takes about 30 minutes.

P1: 5.8, 130’. Gear: Mostly full rack, slings & draws.
Climb a long, sandy left-facing, right-leaning corner. Near the top move right and ascend a hand crack to an obvious tree on the belay ledge. Yuck, this route sucks, just rap off now.

P2: 5.10+, 100’. Gear: 3 of each cam, slings & draws.
Runout, easy climbing up ledgey terrain to the right. Pull a roof (10+) on the right (use long slings), and continue up an awkward lieback crack (10-) to the belay.

P3: 5.11c, 50’. Gear: 4 draws & a #1 Camalot.
Traverse right and slightly down. The hardest moves, a step-down/stand-up sequence, come quickly on the pitch. A bit frightening for the second. The bolts on this pitch could use updating. Continue to a bolted belay on a ledge.

P4: 5.10-, 90’. Gear: 3 of each cam, slings & draws.
Head up and right on a thin flake, then traverse back left below a roof to a corner. A difficult move here (easier if you're tall) leads to a stance below a bolt. Above the bolt, step left to easy terrain (straight up is 10+). Runner gear well on this pitch as it wanders significantly. A bolted belay is above on terraced ledges and the Rocker Block.

P5: 5.12, 100’. Gear: Full rack less the 0.75 Camalot. Slings & draws.
This is perhaps the single hardest move on the climb: A 12b boulder problem off the Rocker Block. My solution was to hang draws on the first bolt or two and carry only one extra draw on my harness, do the moves, then lower a loop of rope to bring up the rest of the rack. In any case, leap sideways off the Rocker Block for the obvious hold up and right. Match, and throw right to a good hold, clip, toe in on the lower handhold, and mantle up to a decent stance. One more hard move leads to a good rest at the base of the long, left-facing corner. Lieback like mad to the anchor – a two bolts out right at a stance.

P6: 5.12+, 100’. Gear: Full rack less the #1 Camalot. At least one sling.
The enduro pitch. The crux of the route is absolutely hanging around placing gear on this sucker. Lieback to a handcrack pod. Place high and continue to lieback through a very thin section to a flare. Some jessery may be possible here, but inevitably, jam upwards, clipping the aid anchor out left along the way (or not), switch cracks to a system on the right and continue to lieback on easier ground up to the roof and a bolted anchor out right. The semi-hanging belay here under the chimney is the only uncomfortable one on the route.

P7: 5.12-, 100’. Gear: Green Alien w/ draw, draw for the bolt, 0.75 Camalot, all 0.5 & 0.4 Camalots. No wires.
This is a great, wild pitch. It is also much harder than the rating would indicate. Place a Green Alien to protect getting into the chimney, and then pull into it and continue up left side in past a bolt. Moving up reminded me of the moves getting into the Harding Slot, more sustained albeit much easier. Eventually the chimney begins to open up into a right angle corner and the knee bars start feeling less and less bomber. A 0.75 Camalot in a pod here protects a strenuous move switching from a knee bar into a jam and then into a lieback. Once liebacking, one can motor up a long 0.5 Camalot section. 0.4’s can be placed higher. Rack on the left side. Climb to the Bivy Ledge and a bolted belay. Crazy exposure!

P8: 5.12-, 80’. Gear: 0.3 Camalots and up, no small pieces or wires.
Splitter rattley fingers. The tough stuff is only about 15'. Bolted belay on a ledge.

P9: 5.12b/c, 110’. Gear: Full rack (including wires) less the #1 Camalot and two of the smallest cams. One or two draws.
Splitter rattley fingers to sit-down rest. The tough stuff is only about 20'. After the rest, a thin crack & pin scars (cool move switching cracks) lead to a bolted belay on a narrow ledge out right.

P10: 5.12a, 190’. Gear: Full rack (including wires).
The Nutting Pitch. Tricky face climbing up the zig-zagging cracks past wedged blocks leads to cruxy, sandy locks to a no-hands knee bar rest. This whole pitch is pretty awesome, and after all the pure jamming/liebacking, the 5.12 face climbing almost feels easy. Almost. Skip the anchor and continue through a sandy 5.10+ roof and on up cracks and knobs to lower angle top out.

Descent: Walk off via the Angel’s Landing trail. This is 2 miles of paved trail to the Grotto Picnic Area which is 1.5 miles down the road from Angel’s Landing. Alternatively, rap (see below). Walking off is much faster.

Miscellaneous notes: The route gets sun at around 9 AM and goes into the shade late in the afternoon. The route can be rapped entirely with a 70m rope except for the second-to-last rappel directly down the face (not following the route). Some creativity here might allow rappel with a 70m rope. Regarding ASCA work: Most of the anchors on this route have been replaced/updated. The route currently needs: the Rocker Block to be re-secured, and for the second-to-last rap station on the face to be relocated downwards by 30 feet or so (to allow rappel with a single 70m cord).


3 each Blue Aliens (equivalent to #0 TCU's)
5 each Green Aliens (equivalent to #1 TCU's)
5 each 0.4 Camalots
6 each 0.5 Camalots
1 each 0.75 Camalot and #1 Camalot (crucial for the 5.11 traverse)
A half set of medium wires (offsets handy)
3 draws and 3 slings
70m rope (if rapping)

Really depends on your tolerance for hanging in your harness on this anchor. Rest of it seems to be nice.

"certainly longest and hardest, sandstone climb in the world."

I'm thinking there are a few free routes in the park that are at least as hard if not harder than Moonlight. Timbertop in Kolob comes to mind.

Thanks for posting up. Free climbing beta is certainly helpful.

In my opinion, he is missing a bit of gear on the rack beta...definitely want at least 2 .75 camalots, and at least (1) 2 camalot. I can't remember if you want a 3, but it would only be on the last 5.10 pitch, and you just styled so many 5.12 pitches, so be the hardman/woman that you just became and run it out - but that pitch feels hard at the end of the day! It is easy to stop the nutting pitch after 90' and belay at the bolted anchor and do a short half rope length top out pitch if you are tired...then you can carry less gear on the nutting pitch! He has listed 6 sets of finger gear, which is good, but you could probably do it with 5. The crux pitch is no harder than 12c, and I have huge fingers - which makes the rest of the route easier.

I would say the 5.10 variation straight up from where over nighters position their haul is much better then the 5.8 to the left. It is more straight forward and takes much better gear then the sandy traditional start. Would be much easier to aid through as well since it actually takes gear the whole way.

The 5.10 variation is where the overnighters will haul for Sheer Lunacy and Lunar Ecstasy. It's better for Moonlight Buttress overnighters to haul in two pitches to the Rocker Block. There is a midway belay station on the face below the Rocker Block. Most will find this a preferable option than hauling the first three diagonal pitches of Moonlight.

Also, the 5.10 variation is a good free climbing option.

We also had a 3 camalot walk and fix itself above the bolt in the flared chimney on pitch 7. It seemed to be really welded, so it will probably stay put. Fixed gear! Yeah!

Big thanks to Josh for all the beta, I climbed it with him the other day and he definitely knows the route. His rack is right on, although maybe a bit heavy on the Blue and Green Alien size. Definitely didn't need anything bigger.

Since people seem really interested in rapping, I'll say this:
The anchors low on the route, below the 5.11 face traverse pitch, seem to have been recently updated. There are two more anchors below the one at the end of the traverse with nice new bolts. Thanks to whoever replaced these.

The only problem is that it doesn't seem like you can rap from here with a single 70m rope. From the traverse, the first rap is only ~15m, but the next one is 40+m. From there to the ground is another ~15m. Luckily for us, just as we were realizing this and thinking of what to do, another party above us rapped past with 2 ropes and so we caught a ride.

Anyways, the anchor positioning makes no sense to me. If the first anchor below the traverse were ~10m lower, everything would be fine and you could rap easily with one rope. Maybe there's some logic to this, but I can't see it. Has it always been this way, or were the anchors moved when the bolts were replaced?

Either way, it's not a big deal, since the walk-off is so easy. I think next time I'll bring a single 50m rope, pitch the route out, and then waltz down in flip flops.

Huge thanks to who ever replaced the bolts, did some anchor upkeep through out the route, and added an anchor at the top of the wall. You even used glue in's :) You Rock!

Not trying to be too provocative, but I just climbed this again the other day, and I'm surprised that this route continues to get a 12+ rating. I think the crux pitch has opened up significantly over the years (though I've only personally climbed it in the last year). Even with my sausage fingers, the crux layback pitch offered good finger locks the whole way. I can only imagine that the constant clean aid and free climbing reinforces and enlarges the existing pin/cam scars.

I don't think that any of the individual pitches would merit even a solid 5.12 grade at the Creek. So sure, maybe the length and sustained nature deserves an inflated "experience grade". I'd be interested to hear, though, from anyone who's climbed it lately what they thought of the crux pitch and the overall difficulty.

Again, I don't want to sandbag anyone or denigrate historic ascents (I'm sure that corner was THIN when Croft and Woodward did it!), but I do want to encourage anyone that feels good on IC 12's to get after it. No matter the grade, it's a stellar

Odd... but maybe I'm not understanding it correctly. John, it seems like you're downrating the route (calling all the 5.12 5.11), but then saying that all those 5.12 Indian Creek pitches are easier? Would that make them all 5.10? I think almost every one of the IC pitches mentioned are harder than the stuff on Moonlight (although, with the exception of Pistol Whipped, those pitches aren't really a good comparison in terms of sizes/style of climbing). Maybe your technique is really good but endurance is lacking? I don't have 0.5 Camalot-sized fingers, and I still find Moonlight to be much easier than 10 pitches in-a-day at the Creek (of equivalent sizes and ratings - and that's including the fact that at the Creek I can return to my cushy puffy jacket and yummy food between each pitch).

My theoretical Moonlight training day at the Creek:

In the morning drive to Broken Tooth and climb Heat Searcher, Inflictor, Polygrip, and Unbelievable. Then in the afternoon head over to the Cat Wall and climb Johnny Cat twice, Kool Cat, and Wild Cat twice. If you survive, you stand a great shot at Moonlight. If you can somehow fit in a redpoint of End of the Line at 2nd Meat on top of all of this, you will most certainly send Moonlight.

Good comments John and Josh, if anyone knows their desert cracks, it's you guys!

Bottom line, this is a stellar route with great gear and continuous climbing, solid at the 12a-12b grade, but enduro rather than cruxy. I think there are a lot of folks you would not hesitate to jump on these pitches at the crag, and they should be even more stoked to get on Moonlight.

Maybe what I'm ultimately aiming to do is shift the perception of MB from a trade/aid route and super-elite free climb, to one that invites more free climbing traffic and ground-up attempts. On this rock, even "clean" aid alters the rock. I'm not saying that no one should aid this route, just as someone could go aid Astroman or the Rostrum if they wanted. But if it could be seen as a do-able free climb for more folks, maybe it would shift clean aid traffic to other routes.

I'd like to say that ticking this route is poor form. I was just up there, and the crux dihedral lieback went as far as to have annotations like "R" and "L". Someone was literally taking notes on the rock. If this thing is that far out of your ability, please stay off the route. The last hard ring lock pitch was pretty ticked out as well with 6" lines marking the pin scars. It's 40' and the scars are obvious. Without tick marks I can see every foot placement and plan out where I'll place gear, before I even start.

Great route, to say the least. I'm still working on the redpoint. That chimney to lieback pitch is the only one that really gives me trouble at this point. It's ridiculously physical and by far the hardest pitch on the climb in my opinion.

Friends of mine who have done the route on numerous occasions over the years tell me that the crack in the crux corner has widened substantially from use. Back in 1992, on the thinnest part, there was a 15' section where I could just force the first pinky knuckle of my right hand into the crack and the rest was nothing more than a tiny bit of first joint flesh and fingernail. My hands are those of an average male.
It is an indication of just how we affect these sandstone routes of the desert SW simply by being on them, and the methods we use for our ascents have various levels of impact on this soft rock. We usually make these choices of our own free will and thus each one of us determines the long-term outcome of the routes over time. Without intending to pass judgement I must make the following observation .... with a paved descent trail coming within 100' of the top of the climb, choosing to rappel the route is one of those high-impact decisions.

For those that are hiking up to the top of the route to rap in and TR solo the route, here's the detailed beta (it's not exactly on Angel's Landing trail):

Hike up the Angel's Landing trail, past Refrigerator Canyon, until you get to the fork at Scout Lookout (obvious cliff vista with outhouse). Going right will take you up the 3rd class trail to the top of Angel's landing, instead, go left at the fork on the West Rim trail for 1/4 mile. I'll post a picture of where you leave the trail.

The bolts are just over the edge, but you'll see obvious rope grooves on the ground from people using the tree to haul.

I don't know if i missed something, but rapping with a 70m did not go as advertised for us. my friends Mammut 9.5 was 30-40ft short on the second to last rap. I knew about this and my Petzl Rope must be longer because it almost reached. however, I would not call that raps with a 70m. I would call that lots of shenanigans, with the potential for a newer party to get hosed. I would assume that we are not alone because we passed 3-4 indeterminate rap anchors in order to reach the last rap.

Since the original post is a bit unclear (gear list says single 70m), you CANNOT rap this route with a single 70m. We tried and came up 10' too short, even while simulrapping. A single 80m would probably be just barely long enough if simulrapping, or two 50m ropes would be fine too. I am not sure why the OP said to bring a single 70m because you dont need anything more than a 60m to lead any of the pitches and a 70m wont get you to the bottom.

As far as shade goes, since someone else asked, the route gets morning sun and starts to go in the shade starting from the top of the route down. Pitches 5 - 10 get shade after about 1:30 PM and the route gets full shade by 2:30-3 PM in April.

I wrote it because I've done it. On one of the final raps you have to swing into the vegetated corner on the right. From there you can continue rapping to the ground. If you want to only use the bolted stations then yes, you need either an 80 or two ropes.

I thought the gear beta was right on, although I was using more camalots and tcu's than aliens. There were quite a few places on the facey crack switch of pitch 9 that took blue tcu's/red c3's in pinscars, but .3 camalots would not fit. I definitely wish I had more of these. Also, if you want one of the worst descriptions of the route ever, which completely messes up the order of the pitches, check this out!

All time classic! I would agree with the rack beta here, we mixed up the small gear a bit and brought some TCUs, C3s , and Master cams as the C4s and X4s don't fit as well in pin scars.

Best to link the last two pitches as one can get a knee bar after the nutting pitch to recover.

I find it odd that no one talks about P4 which is only 5.10 but pretty serious and involves some climbing on a fragile flake and run out above little gear in that flake.

Pitch 6 was grossly ticked. Including".3" written in chalk next to the crack. If you need that much beta and info, maybe you should stick to a easier route instead of covering one of the most classic splitters in the world with tick marks.

I went and did this for a second time, more than 10 years after my original ascent. Man has this thing changed. I remember placing purple tcus on the crux pitch and it being really fierce. Only a couple Red C3's and Yellow C3's now and significantly easier. I'd say it is a stretch to still be calling this 12d. Way closer to 12c or b/c. Still really really fun though!

Here is what I'd bring for a rack if you are comfortable on the grade.

1 Green C3
3 Red C3
3 Yellow C3
4 Grey C4
4 Purple C4
1 Green C4
1 Red C4

We opted to rap the route as there weren't other parties on the wall. We only took a 70m rope. All of the raps are easy except for the second to last rap. We tried to swing right as we'd heard this would make it work. We couldn't find an anchor out there so I just left two stoppers, that I'd actually found in the bushes while rapping. Sure would be nice if the last anchor was just moved up 10 meters. Another option if you plan on rapping is to just bring your tag line up to the rocker block and leave it there. Grab it on the way down and the raps will be easy.

Off the charts good! Absolutely stunning. 6 stars out of 4. Almost got the onsight but fell at the slot pitch crux. Fired it 2nd go. The pinscars are getting pretty blown out from "clean" aid. Aid climbers should find a new route to gang bang, particularly since free climbing has fairly minimal impact on the cracks but relies on them for holds and decent protection. If a weekend climber like me can come this close to onsighting Moonlight with moderate amounts of preparation, why do people still aid this thing? It's not THAT hard! Try it free! Go ground up! Haul your water, jackets, and flip flops and walk off the top!
