Splitter left-leaning finger crack which seemed harder than 5.9 and definitely harder than Bird of Fire. The finger locks were some what tricky and hand jamming is insecure. Use your feet well and the route will seem closer to the 5.9 mark.


This splitter crack is located in Isles Corridor. Approach the Isles in the Sky crag by scrambling up third and fourth class slab. On the ledge where Bird of Fire is, keep walking left around the wall past Dolphin and Nectar. Scramble up and over the slab on your right to find Isles Corridor. Immediately on your left is a 5.2 crack up the slab, which can be used as a descent from the formation. Alternatively, rap or lower from the slung rock above the routes.

The second crack on your left is a splitter hand-sized 5.6 crack. The third crack on your left is Grounder.


Excellent protection the whole way, finger to hand size.

If you have #2 camalot-sized hands you can karate chop the literally every move all the way up. Much, much easier than Bird of Fire for me. Super fun and if it was in a busier area there'd be a queue. 50ft in the Miramontes guidebook. Jul 26, 2017

Very fun, but definitely not harder than bird of fire. Movement is nearly as good though.

Also as of Feb 2016 there's no slings at the top so the downclimb is the best way down. There are rap rings for a route on the other side of the formation if really don't want to downclimb, but it would take a lot longer to make it back to your packs. Feb 19, 2016

I almost never tape at Josh or anywhere else (exception: Vedauwoo). But the rock around Split Rocks area is really agressive, and I'd definitely tape if doing these corridor cracks again. Mar 30, 2009

Grounder is a fun route; straightforward 5.9 in my opinion. May 14, 2006
