This is the short, unprotected, vertical dike at the far right side of the north face of the south formation. It's a cool clean dike and more of a boulder problem than a route. Guide books give it a 5.9 rating, although I haven't checked Randy's latest guide. I thought it was more like 5.7. There is a chimney behind it, that can be used as a descent (easy Class 5).
No pro. Solo or top rope. I couldn't really find a suitable place to set TR anchors, but didn't spend much time looking.
