OK. The Bulge Boulder is a monster of sweet overhung problems, IF you disagree please approach this thing again and see if YOU don't get a Bulge Boulder. The thing is punished by the sun all winter and a few other boulders directly near it make this a flatiron area worth mentioning. Flat landings, great views, and problems from V0 to VStill Wishing await. Mentioned in Horan's Guide with one problem, the thang has 6+. It has amazingly solid holds with the exception being under it's southwest roof, flakey choss.

Getting There 

Park at NCAR. Hike the Mesa Trail North down and over Skunk Creek, up Burly Switch Backs till it levels out and heads East. From here just walk up the bare hill North around a nice warm up boulder nearly trailside. Can't miss it. I would love to see the obvious Bulge problem done from low, if it hasen't already? It is well chalked. Total Approach, probably a mile.

Right of the obvious big bulge problem and left of the warm-up is a gorgeous independent line straight up. starts on a downsloping 10+ finger edge. campus through to crimps above to finish on a beautiful edge at lip. Very hard problem to start, probably harder than V4. I also start this problem from the block system 10 ft. right that is the start to the warm-up. Do a taxing punch left, with or without an intermediate, Heel-hand match to situate. Thing swing feet out left to downsloping edge...[more]   Browse More Classics in CO

I submitted this boulder because of its beauty, winter location, access, and the problem on its south face that I can't do. It is one of the most striking lines in the Flatirons, no doubt. Has widely spaced holds up a giant blank bulge, the big sloping hueco at 10 ft. being the most prominent. The line could and should come from near the ground, but I am years from understanding it. If it has been done, add it, flaunt it, and/or give me a boost off your knee!

The sit start you mention is 'The Zoller Bulge', FA - Justin Jaeger. Maybe V8+ and really good.
