Right of Mangina, lieback the flake to the roof, climb the face above: 100ft to two bolt anchor.
Protection
1 large cam will protect the easy approach climbing to the first bolt then 5 bolts to the ledge, once you gain the ledge clip a directional bolt and traverse left to rap anchor above Mangina.
Key to have a follower clean this b/c of the overhand right below the 2-bolt anchor. Discovered this the hard way while soloing (more of a workout cleaning than climbing!) -- other option is to keep the directional in and just climb it twice. Nice route, though!
