One of the best climbs in the Northwest. For more info consult the Cascades Rock by Blake Herrington.

It also goes free at 5.11.

A final note, you will have to rappel off of the route so be wary of dropping your ropes in the enormous pools of water that form on the ledges.

Approach time is about 2-3 hours.


Gear to 4” with multiples .75”-2.5”, 12 draws, 2-60m ropes recommended

EDIT: Did this route a 2nd time. The first few pitches are often wet. You can bypass the wetness on the first pitch to the left after clipping the first bolt (~5.6) and then up and to the right of the 2nd pitch (look for a bolt in a corner system 5.7/5.8).

While rapping with 60m ropes we linked 18/19, 17/16, 14/13 (short easy downclimb, avoids anchor with missing hanger), 10/9, 5/4, 2/1. Many of these were rope stretchers.

Also for anyone planning to free the exit groove, you'll be climbing a ways above some pretty bad button heads. Sep 22, 2016

Thanks Nate, I made the move. Sep 22, 2016
Hello !! Bill Enger worked w/Whitelaw on the first ascent. Dan Dingle only did one pitch out of the 22!! Bill also did the FA w/Whitelaw on OSO Rodeo.
I was one of several support team members on both climbs.
Great area and GREAT routes!!

Here is a link to a NWMJ article by David Whitelaw about his experiences while putting up Slab Dabby. Great History.

Another trip log (with a few pictures - those slabs look great!) from the First Ascensionist.

Also here is a very thorough thread about this climb. Several trip reports and lots of photos.

Medosch, your beta is incorrect. I climbed all of the pitches, the first half of the climb multiple times. I bolted on lead all of the 12th pitch and part of the 13th. Bolts were later added to the 12th so a leader wouldn't be mortally wounded, especially if popping off the mantle far above the first bolt. It was a great route and time with fellow adventurists Whitelaw and Enger. Sep 6, 2017

A couple of updates on conditions:

There's now a large downed tree just upriver which makes the crossing much easier. The slide path is heavily overgrown which can make some of the route finding harder. The second bolt on pitch 3 is missing a hanger. The belay station on pitch 13 is missing a hanger and has a rusty nut + carabiner instead. Oct 15, 2018
