This is one of the classic crack boulder problems in the Valley. Approximately 20' tall with a short approach, flat landing, and easy walk off, this slightly leaning splitter finger crack is great for honing your thin fingercrack technique. Mostly first knuckle locks. Usually bouldered, but you could rig a TR if desired.

"Climb the beautiful splitter finger crack that angles up and left.
First 5 feet are the hardest by far." - ShaunG Gregg


Walk behind wooden cabin #20A in Half Dome Village straight up the hill to the trail through the trees that is leading up towards the side of the mountain. The boulder sits near the base of the mountain wall.


Pads and spotters.

Be warned that the last move has spit off many unsuspecting climbers. While the move feels quite solid, I have heard of at least 3 different people taking the fall and fuck'n up their ankles.

I'm a trad climber. What is this in YDS? I originally heard it was 5.10d but every conversion chart I've seen would place V2 at 5.11a/b to 5.11d, more consistently at 5.11+/5.11d.

Really fun. 3 move crux then it gets gradually easier. It leaves your finger tips feeling hot!

I was looking for this problem a week ago and didn't think about the rockfall a couple years ago. Evidently it took out most of the cabins back there. Can anyone give some beta about how to find it now days? Thank you!

There's a climbers trail leading up to the base of it. The trail begins a little bit to the east of the Old Curry Area (Root Canal, Kevin's Traverse, ect...) It's been a few years since i walked up there so I don't remember the specifics other than that.

There's also some more photos and a video on the route page under the bouldering section: ??

Good catch, Bryan. Since people haven't been finding this route in this area, I'll move it to Curry Village bouldering for now, and merge the newer version of this route's data into this original object.

I'll leave the Staircase Falls area though, so people can add the routes on the wall itself later.

This is a fun problem and worth the short hike up. Low crux with a heady topout. Im told the line just left goes at 5.12.

Since the buildings are gone (see my comment on the Curry Village page), if you're looking for the Circuit Breaker, stay left at the trail junctions (as you're working your way east). When you cross a ditch over an unexpected, small, stone bridge, take the climber trail that heads off to the left (uphill) immediately afterward.

Josh, I believe there's a slight correction/clarification to your directions; when you cross the small stone bridge, you're headed West, not East.
