Access Issue: Temporary Trail and Raptor Closures Details


The Slab has many lines but none are too distinctive, especially those like this one in the middle of the face. Hike up the approach trail from the Shanahan Trail. On the approach, look for an odd gnarled tree somewhere in the middle of the summit ridge of the slab. It sits alone and half of it is dead, it's about 20' tall. This tree is a landmark of the route, and (when you can see it) you want to navigate more or less straight at it.

When the trail nears The Slab, hike off left along the base. Very soon you will reach a large, south-facing dihedral, the route begins about about 150 feet south of this dihedral system.

In this area, there is a problematic vertical wall/overhang about 70' up the face, which becomes more significant farther left. The easiest line is not obvious in here, just start up and head right if it is getting too hard (or unprotected) for your tastes.

After you pass this initial steep section, the climbing becomes easier. Head up and left. After about 3 pitches from the ground, you should be able to see the grarled tree. This face is rather indistict and nearly impossible to describe an exact line, just head for the tree. After the tree, head south on the summit ridge. Downclimb off west or continue to the summit (both described in more detail under the route "Diagonal").

Can be very easy to get off route and into more serious or difficult climbing. I don't think I've ever found a 5.2 way up it. Nov 11, 2007
I believe I started at in the correct area for this climb, but I am guessing I did not follow the route, as I encountered very little 5.2 climbing. MUCH harder than Diagonals or some of the other 5.2s on the Slab. That being said, it was also probably the most fun I have had on a Flatiron solo. I think most of the climbing I did was in the 5.5-5.7 range, I mostly stuck to the steeper lines. The climbing is great, lots of juggy, steep, even some short overhang sections with slab interspersed. A bit different from a lot of the east face Flatirons I've done. Plus the Slab doesn't see as much traffic as the other popular solos, and the view from the rock is great. Jun 28, 2013

This route would be no fun for somebody just getting into Flatiron ambling. For the grade, it is steeper and runout when compared to other Flatiron slabs with the same rating. I'm pretty sure that we followed the Gerry Roach description to the T. The crux bulge is short with a decent piece at your feet, but the rest of the route is essentially pro-free and finding the easy way is not obvious at all while on the expansive face.

That said, this really was an enjoyable outing and a route I will likely repeat. We made the tree on the summit ridge in two 180' pitches and a third 350' "pitch" (simuled). Dec 6, 2014
