This is accessed from the Agnes Falls trailhead up Chalk Creek Canyon, just outside of Buena Vista. Go up past the Mt. Princeton Hot Springs and past Mt. Princeton campground. The pullout is just to the right of Chalk Creek Campground. If you go over a bridge or see a lake on your left, you've gone to far. It has BOMBER granite, tall problems, classic slab problems, and another classic dihedral. It is SECLUDED.
Hike up around 100-150 yds, and you will see it through the trees on your left.
Love this boulder. I have been climbing on it since the late '90s. I called it the Big Agnes. Did a few classics on the west face, but never had the nerve to do the high ball 2 lines right of the "Sorrowful Journey". The line goes up the shallow dihedral and angles up and right, following the black streak. Bold moves to top out. I have some other projs nearby. I will post soon.
Try these lines too. "B" is scary. First moves are burly.
