Yeah, it was the notch section (and the photo really makes it look like a walk, but actually it required a lot of mantling and other climbing techniques) which in combination with the exposure, I think, classifies as class 4 (beginners might want a belay). But in retrospect since it was just a very short section it could be considered class 3. We watched the summer camp group descend and they basically passed the kids down from one grownup to another!

I should also point out that we, um, didn't quite go the best way through the notch on the way up, and found an easier descent.
