A New England classic. Head straight up and out the overhang. Many different sequences will get you most of the way up the boulder, but the crux for most will be the last couple moves, when you can no longer keep your feet down low.
Apparently this was originally a v8 when Sherman sent it, using a blowtorch to dry the holds. The upper jug exfoliated, leaving the problem in its current state. Dave Graham got the first re-ascent.
As I understand it, Satan on a Half Shell starts about in the middle of the boulder and follows a vertical rail feature up until you traverse a few moves left, set up on crimps, and chuck for the broken hold.
Satan's Sister Sally starts further left and moves straight into the same dyno using a right hand crimp and left hand slot.
