Yesterday was my first trip down Waterton ever, and it was a lot of fun.
I can't tell you if the guage is right, but the guy I was with seemed to think it was. Upper section was continuous III, pretty fun. Lower section was four features that were probably III+ or IV- (the first I'd say IV- for sure). I'm just moving up to IV-ish stuff, so I'm not a good judge.
It was a freakin blast though, took all the skill I've learned thus far in the lower section. Short. We ran the lower part twice before hiking out.
"self-aggrandizing jackass" - it says it right on the label
