Cool climb up a corner to start. The first 30 feet are the crux. Tight hands and some hard moves at 10b. After that, sustained 5.9 but tons of fun. Cool rock.

Rap chain anchors 


Right of Lunatic Fringe in a clear spot. Look for the amazing small corner.


Doubles to #2 C4 Camalots.

Burly and historic route.

FA: Jim Bridwell & Galen Rowell, 1971. Near the cutting edge of free climbing in that era. Important to include the history of these climbs. Apr 22, 2007

A great route with excellent protection throughout. A bit too short for true "classic" status, but still really good. Aug 15, 2007

VEry fierce and classic climb! Takes good gear all the way.Once through the crux the climbing is straight forward sustained all the way to the top! Done it a couple of times. Feb 26, 2008

The second pitch should not be forgotten. 5.8 hands in a right facing corner! If pitch one is too short, then do both pitches in one. May 30, 2010

In the Sierra Club's mountaineering journal, Ascent, 1973, Jim Bridwell proposed letter grades for 5.10. His examples for 5.10a thin cracks were; Stone Groove, Swan Slab (P2), Sacherer Cracker, Siberian Swarm Screw, East Corner of Higher Cathedral, and Central Pillar of Frenzy (p2 & p6). Jan 31, 2011

Ken - In no way am I in the position to question Bridwell, but I think a lot of folks would agree that Stone Groove is harder than anything on Central Pillar of Frenzy (first 5 pitches, anyway). May 8, 2011

Indeed. Stone Groove is substantially harder than p2 on Central Pillar. May 13, 2011

Cruxes were a bit easier than Lunatic Fringe, but this route felt much more sustained and insecure on the jams.

The top anchors can be reached by a fun 5.9 variation around the corner to the right that is worth doing in its own right (I'd give it 2-3 stars). Bring pro through #4 BD C4 and be prepared for some sustained & steep jamming, with occasional surprise stems to keep things reasonably easy. There is a little loose rock that is easy to avoid, and a fun lieback on a hollow flake (1-2 #2 C4s) that transitions to a bear hug & mantle to finish.

The second 5.8 pitch above Stone Groove is a LOT harder than the 5.9 approach pitch and it is not hands (well maybe the first part is). It is a very tight & flaring squeeze chimney that takes good elbows-up chikenwinging. There is no pro except for sliding a #6 BD C4 until you reach the chockstone near the top (takes a #1 BD C4?). If you have good flexibility you can reach around and place a small cam in a dirty seam behind you to backup the #6, though it might not hold much of a fall. The #6 is barely large enough to protect as it is slid along or re-set beyond the wider parts. The crux is getting through where the chimney widens just before the chockstone. This pitch was short but burly and very worth doing! (3 stars) Bring minimal pro, as gear definitely gets in the way leading this pitch.

Rap anchors for the 5.8 P2 are old and need replacing. We added some new webbing to tie elements together and added a rappel ring. The top shares the same belay as one of the pitches of the Rorp (5.7) so this route could be TRed from this alternate approach or used as a part of a very lengthy but 5.5ish way to set up a TR on P1 of Stone Groove.

No need to do any silly variations or anything, this thing protects very well and is a blast (not to mention quite fierce, in that classic friendly Yosemite way). Only reason not to get on it might be crowds, but we didn't encounter any on a gorgeous Sunday in early November... Nov 5, 2012

I'm not the best crack climber, but I found this to be really sustained due to virtually no left feet. For my large hands, the hand jams were generally good most of the way, but where the crack was more constricted and the jams tentative, it felt super tough. Seemed like the key was to read the crack carefully and foot jam high in spots in order to skip over the tough hands portions.

I read that the "roof" portion was the crux, however again with large hands, I did not find this to be true - the narrower crack down low was harder. Above the roof, the terrain felt generally easier.

Pro is definitely bomber just about all the way, so good route on which to push your limits! Apr 28, 2013

The beginning is kind of funky. Once you break through that it is mellow. Dec 12, 2016

The thin hands will feel spicy if you have fat hands like me. Still easy to finesse through though. Feb 12, 2018
