Yes, that is seriously the grade. A creative diversion while in Valle Trinidad, boulder up the vertical face of the boulder (V3), top out and clip a sling onto the bolt a few feet below the crack. Step into the sling (A0) and start the thumb stack, thin hands crack (5.11) out left until it tapers off. Move up to anchors about 10 meters up from there.
(I hope someone frees the bolt protected moves and gives this a little better grade...I'm guessing 12+, maybe?)
