Still trying to figure out the crux.


This is another good route on the Iron Side Wall of Monitor Rock. This route is located just right of Prospector and shares anchors with this route. The crux comes between the 2nd and 3rd bolt, and there is a slight run between the 3rd and 4th bolt that would probably take a black/blue Alien or equivalent. The climbing eases a bit here, but just throwing it out there, since I wouldn't want to blow the 4th clip.


It is just right of Prospector on the Iron Side Wall. This route follows a tiny seam up a black water streak.


7 bolts to a 2 bolt cold shut anchor. Maybe a blue or black Alien size for the spacing between the 3rd and 4th bolt.

This route seemed as hard or technically harder than the route rated 11c to its right.

I would have to agree with Bob, the climbing between the first and second bolt is very thin, sequential, and crimpy. Much harder than Molly Brown, the 11c to the right.

Lee, thanks for helping me regain some measure of self esteem! This climb made me feel like I must suck worse than usual with all the hanging and whimpering I did on the first 2 bolts. 11a....

I would have to agree with all of the above comments. I was quite tired and feeling weak today, but I can on-sight 11a sport climbs most of the time, and when I don't on-sight them, I almost always get the red point on 2nd go. This route kicked my butt. It took me about 6 tries before finally getting the redpoint. Climbing is always a humbling sport, but I think this is harder than 5.11a. Either that or I just got handed a big slice of humble pie. Hard or not, this was a fun climb to work on.
