This climb is not as popular as Regular route for its X rating, so you don't have to wait much in line if the first pitch is dry and you can run it out pass the point where Regular branches out. Small gear, but you may want to bring gold and blue camalots for anchors. Off-width protects nicely with small gear, but if you're not sure, you can bring a #4 camalot - it gets pretty windy on that arete. Watch out for those crumbly flakes - my partner broke off a huge piece while holding onto one.

A fantastic climb, but as the description says be sure that at the base of the X pitch begin straight up from the perch, do not traverse right to the fixed gear, if you do there are no feet and traversing into the main line is a little dicey. A great climb for someone solid on slab and solid in the mental aspect of climbing haha.

As Adirondack Rock mentions, I'd avoid belaying at the top of the OW. A fall on the runout and unprotected slab directly above would be directly on the anchors. Keep going up another 40 feet and belay at the obvious vertical crack at the overlap.

Once you are past the OW it gets really run out. We were not expecting there to be almost zero protection but that is most certainly the case.

Awesome varied route. I think it gets my nod over the regular route in everyway, except the gear rating i guess :)

About as varied climbing and terrain you could have given that it's all still a friction slab.

P1 - nice warmup of friction -- check if your head is ready today for what lies above. Careful not to make the anchor too high, or you'll have to down-climb to the "steppy" rock that starts the next pitch.
P2 - different rock textures ... right across the "steppy" rock, then up white-ish rock to make an anchor near base of giant L-facing corner.
(? alt P2 ? The reason not to go directly to the bottom of the crux pitch P4 is then you miss out on the interesting rock types and features that make this route different from most slab routes).
P3 - up a little along the giant L-facing corner, then out left before it overhangs, and keep traversing ... first across the low part of a thin flake, then up onto th first hump, below a second (less distinct) hump, and finish on top of third hump.
P4 - pretty much straight up, perhaps trending a little left toward the off-width. The reason it's rated X instead of the usual friction slab R is because if the leader falls, it's not just a long slide to the end of the rope -- rather the fall comes done hard onto a substantial rock ledge with a big elevated lip - (or smashes onto the unfortunate belayer).
P5 - I thought the off-width was pretty fun with my feet outside it on its left side the whole way up -- nice way to retain the character of the route as a friction climb. Anyway followed by another runout friction section up to a obvious (but narrow) overlap.
P6 - less steep friction up to a big stone lying on the surface, with trees nearby to right.
P7 - we were taking the north descent, so we traversed right (actually the easiest line seemed a little downhill at first) to the right side of the slab to the trees, found an informal trail up thru trees and across exposed rock sections obvious to the (non-trivial) north descent.

Super classic friction route; definitely NOT for beginning or shaky leaders. Two spots, as mentioned, would be terrible fall zones: the third pitch's 90' runout, and after stepping off the block above the big crack.
