The Dihedral 

the best? i dunno man, the whole thing is slick as snot and I don't think i'd put beginning leaders on it just because of it.

Although I gave this route a 4 star rating, it is mostly for historic value. Don't be fooled into thinking that this route is the best 5.6 in Oklahoma, let alone the nation. In fact, here is a list of better 5.6's that first time leaders can be psyched on:

Yee Haw; Upper Mt. Scott (3 freaking star route for sure)
Side Saddle: Zoo Wall left
Great Expectations; Elk Slab
Large Corner Girdle; Lichen Wall

Get out and do these routes before you slide off the Dihedral grease-fest!

I've never heard anyone call it the best 5.6 in the state. All the same, not a terrible climb, but the rest of the climbs on that face are much better.

Grease fest? I don't recall this route being slick at all. Climbed it twice without any problems. Second time was on TR hauling up as fast as I could to photograph a climber on Crazy Alice. I have heard this is more of a "Level 2" newbie leader climb though, but mostly because of the ledge and use of runners.

honestly, this route blows like gums mcgee. It's slick, it's wide, and it's awkward at the bottem. Yuck. Great Expectations is a helluva lot more fun.

If this is the best 5.6 in the nation, American route developers have some serious work to do.

Great classic route. Rating is more around 5.7 now because a lot of moves are polished and the move coming out of the roof is more of a 5.7 move as well. Done this as a second and on lead.

Route can give new leaders a run for their money, there is potential to fall on ledges all the way up, so be careful when protecting. It doesn't hurt to have a #4 on this route either, maybe even two. I think I only placed one though.

Felt like 5.7 to me. Similar difficulty to Yellow Corner, and harder than the other 5.6's in the Narrows due to being off-width and slick.

Point taken on this not being anywhere close to the best state or even area... I have no idea where I'd think I read that from? Great alternative choices for other routes. Now I must contest the assertion that it's a 5.7, because it has jugs the whole way, a no hands stance every 8-10 feet, the crux is all jugs, slick rock isn't a problem given all the back step opportunities.

I knew I read it somewhere.... "The Dihedral is one of the best 5.6 climb in the southern U.S." - Chuck Lohn author of "The Oklahoma Climber's Guide

Felt like 5.7+ to me, falls were not clean as mentioned above. It's not really a crack climb, I used more liebacking and face climbing. I'd highly recommend Crazy Alice over this climb if you feel confident at 5.8 and are looking to jam
