Mystery Jam is the obvious line at Isabella. Start on the face to a cruxy throw. Work your way up to the beautiful crack. Continue up past a few committing jug moves to easier ground. The top is marked by a fixed nut and pin.
This route is at Issabella, not Palmer. Continue driving down Isabella (past the turn to Slugg's Bluff) for 3 more minutes. Take your first left on a dirt road, then your next right. Drive though a field to the cliff. First major route you will encounter
set of nuts, .3-3, few draws
