On the Citadel Boulder it is the far right arete with a small scoop at the start, it starts on two of three crimps and climbs up to a jug rail and topout. Don't fall in the summer. You may end up in the creek.
I never tried "Surface Tension" before the hold broke off, but the water was low enough for me to try the line, and it seemed like it may still be around V10 or so. Maybe V11? I'm not sure. I am so bad at grading lines. Some 8-9's and even harder I can get without a lot of fuss and others many take weeks or longer, crazy. It's just style, I guess?
I didn't send but linked all the movement except for the matched 1st crimp pushing out of the scoop to the kinda "U" shaped (R) hand crimp on the lip of the arete/scoop. I could do that single move but not the total link-up.
I think I could send next time out? I would still call it V10'ish unless I'm doing something wrong? Anyway, it's a cool line if the water is down. And the logs really help with the spot pads. I dig it!!
Checked it again with no send but it does not seem like it's going to be V11 hard but what the hey.... I still need to send it. Water is low enough to do it for sure. I feel close to getting this one. Really just one move shy. Cool line for sure!!
