The crux of Molar Concentration! How many mol...

Kind of a "rules" problem just to the left of Composure's corner. Nice thin crack climbing...balancy.


Just to the right of Aerial's arete and left of Composure is a crack system going through a small (2') roof. Climb it.


some 3" for the bottom, then some hand and finger stuff for the top.

The top of this climb makes it worth doing. I found it an interesting and balancing crack.

I climbed Composure on 05/28/17 and on my way to the top noticed that the bolts for Molar Concentration don't have hangers anymore. The bolts were still there and looked shiny and relatively new, and I didn't notice any chopped bits of metal or anything. But there were no hangers, so nothing to use for lowering/anchoring.

You could also finish by going up the last chunk of Composure and walking off the top. Just don't expect a bolted anchor at the top of this climb as of May 2017.
