This is an obvious, left-angling crack that climbs a wee bit harder than it looks.
Start to the right of Tunnel Vision, move up to the left-angling crack. Figure out a way linking some fragile-appearing holds to mostly left of the crack. You can jam the crack a bit. Once the left-angling crack disappears, wander up and right on easy terrain to the rappel tree.
Rappel ~90' from a sling and link around a tree.
This is on the left side of Pulpit Rock between Tunnel Vision & Anatomically Incorrect.
Rack up to a #2 Camalot. A pink tricam can be useful.
